Boryl radicals have become indispensable in organic synthesis, yet, translating their complex steric and electronic properties into actionable reactivity insights remains challenging. Herein, we present a comprehensive classification of boryl radicals, including a publicly accessible database of 141 neutral 7e-4c boryl radicals, each parametrized by a set of electronic and steric features derived from DFT calculations.
Unsupervised machine learning (k-means clustering) and dimensionality reduction (PCA/UMAP) condense this high dimensional descriptor space into the “B-rad map”, capturing trends in sterics and electronics among the resulting five clusters. Global electrophilicity (ω) and nucleophilicity (N) indices are overlaid to create a polarity‑annotated guide, while DFT‑computed activation free energies for six benchmark reactions (HAT, radical addition, and XAT for two different substrates) yield the React‑B‑rad maps that directly link intrinsic properties to specific reaction performance. To demonstrate predictive power, supervised machine learning models (random forest) are trained on the descriptors and successfully predict radical reactivity regimes across all reaction types.
Overall, this integrated, machine-learning-driven platform can serve as both a practical guide for experimental decision-making and a foundation for data-driven discovery, paving the way towards rational design and virtual screening of boryl-radical reagents for diverse synthetic applications.

Here we propose a latent variable approach that bridges the gap between ligand-only data and protein–ligand complexes, enabling target-aware generative models to explore a broader chemical space, thereby enhancing the quality of molecular generation. Inspired by quantum molecular simulations, we introduce ECloudGen, a generative model that leverages electron clouds as meaningful latent variables.
ECloudGen incorporates techniques such as latent diffusion models, Llama architectures and a contrastive learning task, which organizes the chemical space into a structured and highly interpretable latent representation.
Benchmark studies demonstrate that ECloudGen outperforms state-of-the-art methods by generating more potent binders with superior physiochemical properties and by covering a broader chemical space.

The increasing complexity in designing nanostructured materials for electronics, biomedicine, and energy applications requires advanced computational methods to enhance research efficiency and minimize experimental costs. This study proposes an innovative agent-based retrieval-augmented generation (RAG) system integrated with large language models (LLMs) to automate the extraction and analysis of scientific information from extensive literature databases, specifically targeting nanostructured materials developed via two-photon polymerization (2PP). In addition to extracting and analyzing scientific data, our approach emphasizes understanding how these nanostructured materials interact with cells, which is crucial for controlling their application in biomedicine.
The developed platform demonstrates robust semantic accuracy (cosine similarity: 0.82) and high overall task precision (0.81), significantly reducing the likelihood of misinformation by incorporating dynamic query refinement mechanisms. The intuitive, user-friendly interface facilitates quick access to relevant scientific data, thereby improving researchers’ productivity and enabling more accurate experimental planning. Although the system exhibits certain limitations regarding domain-specific terminology coverage, further fine-tuning and specialized training are anticipated to enhance its performance and reliability for advanced scientific applications.

Polar organic cocrystals hold significant promise for various advanced technological applications. However, their relatively low occurrence emphasizes the difficulties in achieving the desired polar packing arrangements, making their discovery complex and challenging.
Here, we introduce a data-driven method that combines machine learning (ML) with high-throughput (HT) automation to speed up the discovery of polar organic cocrystals. Using ML techniques, we identified key factors that influence polar cocrystal formation, allowing for targeted selection of molecular candidates. We examined 13 cocrystal combinations with chloranilic acid (CA), screening 20 solvent systems for each, which enabled a highly efficient search across a broad chemical space. HT automation further enhanced the synthesis and characterization by enabling rapid screening and precise structural validation, while thoroughly exploring the chemical landscape. Experimental results confirmed 13 pairs of CA cocrystals, with 6 crystallizing in polar space groups, resulting in a polar discovery rate of 46%-nearly three times higher than the average in the Cambridge Structural Database (CSD) (∼13.2%). This integrated approach offers a new strategy in polar organic cocrystal research. The findings demonstrate the potential of this method to advance functional molecular materials and pave the way for next-generation applications using polar organic cocrystals.

Artificial intelligence (AI) is transforming research in metal–organic frameworks (MOFs), where models trained on structured computational data routinely predict new materials and optimize their properties. This raises a central question: What if we could leverage the full breadth of MOF knowledge, not just structured data sets, but also the scientific literature? For researchers, the literature remains the primary source of knowledge, yet much of its content, including experimental data and expert insight, remains underutilized by AI systems.
We introduce MOF-ChemUnity, a structured, extensible, and scalable knowledge graph that unifies MOF data by linking literature-derived insights to crystal structures and computational data sets. By disambiguating MOF names in the literature and connecting them to crystal structures in the Cambridge Structural Database, MOF-ChemUnity unifies experimental and computational sources and enables cross-document knowledge extraction and linking. We showcase how this enables multiproperty machine learning across simulated and experimental data, compilation of complete synthesis records for individual compounds by aggregating information across multiple publications, and expert-guided materials recommendations via structure-based machine learning descriptors for pore geometry and chemistry. When used as a knowledge source to augment large language models (LLMs), MOF-ChemUnity enables a literature-informed AI assistant that operates over the full scope of MOF knowledge. Expert evaluations show improved accuracy, interpretability, and trustworthiness across tasks such as retrieval, inference of structure–property relationships, and materials recommendation, outperforming standard LLMs. This work lays the foundation for literature-informed materials discovery, enabling both scientists and AI systems to reason over the full existing knowledge in a new way.

As a major burden on global healthcare systems, adverse drug events (ADEs) result in significant morbidity, mortality, and healthcare resource consumption. With the rapid advances in precision medicine, personalized ADEs and their molecular mechanisms are important components of drug repurposing and drug safety improvement. Thus, extensive studies have been conducted to collect valuable information on personalized ADEs, but no database has yet been available to provide such data.
In this work, PersADE, a database aiming to provide personalized drug adverse events and their molecular mechanisms, was constructed. It integrated 4 061 772 personalized drug-ADE associations, 31 756 protein-ADE associations, and 108 677 drug-protein interactions, with a particular emphasis on off-target effects.
The uniqueness of these data lies in (a) providing demographic characteristics, disease context and drug administration parameters associated with ADEs, enabling stratification of drug-ADE associations; (b) systematically integrating interactions among drugs, human proteins and ADEs, describing the mechanistic insights. Given the growing global focus on precision medicine, PersADE is highly anticipated to significantly impact studies on personalized ADEs and mechanistic explorations by providing researchers and clinicians with evidence-based tools.

A domain-specific large language model, MOFs-LLM, is developed to accelerate the inverse design and synthesis of metal—organic frameworks (MOFs) for hydrogen storage. Trained on 210 million tokens derived from over 6 000 MOF-related publications and 15 000 crystal structures, the model integrates chemical knowledge with structural features to improve structure–property reasoning. Compared to baseline methods, MOFs-LLM achieves a 46.7% enhancement in capturing structure–property relationships. It enables the inverse design of 60 candidate frameworks optimized for both hydrogen storage performance and synthetic accessibility.
Guided by the model, a novel MOF (Cu-LLMs-1) was synthesized in three experimental iterations, exhibiting a hydrogen uptake of 1.33 wt% at room temperature, ranking among the top five pure MOFs under comparable conditions. These findings highlight the potential of domain-trained language models to bridge virtual screening and experimental realization in materials discovery.

We provide an overview of core molSimplify functionality and recent updates that enhance its capabilities for automated molecular and materials modeling. We describe the mol3D and atom3D classes, which store atomic and bonding information for a wide range of functions, including reading, modifying, and characterizing molecular geometries from common file formats. Enhancements to decoration and substructure addition functions enable systematic derivatization of template molecules.
We introduce a new mol2D class that enables graph-based uniqueness checks and substructure identification. Most importantly, we introduce improvements to transition metal complex (TMC) generation that eliminate steric clashes and enable structure building with ligands of higher denticity. Integration with machine learning models that predict coordinating atom identities enables truly high-throughput, de novo TMC generation.
We describe applications of molSimplify outside of isolated TMCs, including extensions to periodic systems (i.e., particularly metal–organic frameworks) and to metalloenzymes through the protein3D class. We demonstrate our improved combined structure prediction and generation workflow by generating structures of a database of experimentally characterized Ir complexes from only the SMILES strings of their respective ligands.
We envision that recent enhancements will make the code easily extendible to other periodic materials such as covalent organic frameworks and zeolites or to multimetallic transition metal complexes.

Validating chemical synthesis success requires confirming the desired product using various analytical techniques. While spectroscopic data collection is increasingly automated, interpreting results remains a major bottleneck, often requiring expert input. With advances in laboratory automation and high-throughput synthesis, this challenge is expected to intensify.
We introduce the MultiModalSpectralTransformer (MMST), a machine learning method that predicts chemical structures directly from diverse spectral data (NMR, IR, and MS). Trained on 4 million simulated compounds, MMST achieves 72% and 80% as top-1 and top-3 accuracy, respectively. To address out-of-distribution challenges, we implemented an active learning improvement cycle that generates molecules in similar chemical spaces, enabling the model to adapt to chemical structures beyond its original training data. We demonstrate MMST's capabilities through comprehensive benchmarking across diverse molecular weight ranges and chemical spaces. Notably, despite training solely on simulated data, MMST demonstrates good performance with experimental spectra. This research represents a significant advancement in automated structure elucidation, offering a powerful and adaptable tool that bridges the gap between simulated and real-world data.

The disconnect between AI-generated molecules with desirable properties and their synthetic feasibility remains a critical bottleneck in computational discovery of drugs and materials. While generative AI has accelerated the proposal of candidate molecules, many of these structures prove challenging or impossible to synthesize using established chemical reactions.
Here, we introduce SynTwins, a novel retrosynthesis-guided molecule design framework that finds synthetically accessible molecular analogs by emulating expert chemists' strategies in three steps: retrosynthesis, searching similar building blocks, and virtual synthesis. Using a search algorithm instead of a stochastic data-driven generator, SynTwins outperforms state-of-the-art machine learning models at exploring synthetically accessible analogs while maintaining high structural similarity to original target molecules. Furthermore, when integrated into existing molecular property-optimization frameworks, our hybrid approach produces synthetically feasible analogs with minimal loss in property scores.
Our comprehensive benchmarking across diverse molecular datasets demonstrates that SynTwins effectively bridges the gap between computational design and experimental synthesis, providing a practical solution for accelerating the discovery of synthesizable molecules with desired properties for a wide range of applications.

The application of machine learning approaches to meaningful problems in chemistry and materials science is still challenged by the limited availability of data. In order to close this gap, we report the tmQMg* data set, which provides excited state properties for 74k mononuclear transition metal complexes extracted from the Cambridge Structural Database. All properties were computed at the TD-DFT ωB97xd/def2SVP level of theory. The strongest electron excitations in the ultraviolet, visible, and near-infrared ranges are included, together with the wavelengths and intensities of the first 30 excited states.
Further, natural transition orbitals were computed for the strongest excitations in the visible range to determine the nature of the associated charge transfers. By computing the TD-DFT spectra in both gas phase and acetone, we quantified solvatochromic effects, which are also provided with the data set, in terms of both wavelength shifts and intensity changes.
The tmQMg* data set will enable the development of discriminative and generative artificial intelligence models with respect to absorption spectra, charge transfer character, and solvatochromism, enabling novel advances in the field of transition metal photochemistry.

In this paper, we present the results of training machine learning (ML) models for accurate prediction of several key photophysical characteristics (absorption maximum wavelength, molar absorption coefficient, emission maximum wavelength, fluorescence quantum yield and lifetime, singlet oxygen generation quantum yield) for BODIPYs. ML models were trained using experimental data comprising more than 35,000 records for the predicted parameters. Particular emphasis was placed on model interpretability and on accounting for the solvent nature effect on the predicted photophysical parameters. To ensure open data access and a user-friendly interface, all developed models were integrated into the created web tool SpecML (http://specml.isc-ras.ru/).
SpecML allows prediction of photophysical parameters for individual BODIPY molecules and the screening of entire series of BODIPYs. We believe that our created SpecML web tool will become an effective resource for accelerating the rational design of BODIPYs with desired photophysical properties and will be useful for a wide range of researchers in the fields of photonics, organic electronics, and molecular design.

Machine Learning-Assisted Crystal Structure Prediction of Solid-State Electrolytes Reveals Superior Ionic Conductivity in Metastable Edge-Sharing Phases
https://doi.org/10.1021/jacs.5c15665
📕 Journal of the American Chemical Society (IF=15.6)
#method
https://doi.org/10.1021/jacs.5c15665
Significant attention has been devoted to developing novel solid-state electrolytes (SSEs) with high ionic conductivity for all-solid-state batteries (ASSBs). However, most studies have primarily focused on compositional substitutions, often overlooking the fundamental role of inherent crystal structures on ion transport.
To address this, we introduce a theoretical crystal structure prediction (CSP) approach based on the machine-learning moment tensor potential (MTP). The proposed approach successfully identifies novel SSE structures and reproduces 12 experimental crystal structures. Using a phase-diagram-guided strategy, CSP is applied to four promising SSE candidates, Li2SiS3, Li2GeS3, Li4SiGeS6, and Li4SiSnS6, to assess their polyhedral connectivity, relative stability, and Li-ion transport properties.
The results reveal that metastable edge-sharing phases exhibit superior Li-ion mobility compared with their stable corner-sharing counterparts. This superior conductivity is attributed to the Li-ion accessible volume, quantified by the packing ratio (fraction of the unit cell volume occupied by nonconductive volume) and by the dynamic distortion of the Li–S4 sublattice, which represents the local environment encountered by migrating Li-ions. The metastable phases feature higher packing efficiency, larger Li–S4 sublattice volume, and greater distortion, all of which contribute to improved Li-ion transport. This study highlights the potential of CSP to design novel SSEs and high-performance ASSBs.

Многие из вас помнят наш датасет по растворимости BigSolDB 2.0, который мы опубликовали в июле в Scientific Data📕 .
У BigSolDB был один принципиальный недостаток: он не покрывал случаи, когда соединение растворяется в бинарной смеси растворителей, а текущие датасеты (BaoDB, MixSolDB) — на наш взгляд, были слишком небольшими для ML.
Поэтому мы решили собрать самый большой в мире датасет по смесям бинарных растворителей. Так и получился MixtureSolDB.
В него входит:
— 175626 экспериментально измеренных значений растворимости
— 813 уникальных соединений
— 750 уникальных бинарных смесей растворителей
— 3023 уникальные системы растворённое вещество – бинарная смесь растворителей
— данные из 1119 рецензируемых статей
Датасет подходит как для обучения и сравнения различных ML-моделей, так и для прямого анализа экспериментальных данных.

Многие из вас помнят наш датасет по растворимости BigSolDB 2.0, который мы опубликовали в июле в Scientific Data
У BigSolDB был один принципиальный недостаток: он не покрывал случаи, когда соединение растворяется в бинарной смеси растворителей, а текущие датасеты (BaoDB, MixSolDB) — на наш взгляд, были слишком небольшими для ML.
Поэтому мы решили собрать самый большой в мире датасет по смесям бинарных растворителей. Так и получился MixtureSolDB.
В него входит:
— 175626 экспериментально измеренных значений растворимости
— 813 уникальных соединений
— 750 уникальных бинарных смесей растворителей
— 3023 уникальные системы растворённое вещество – бинарная смесь растворителей
— данные из 1119 рецензируемых статей
Датасет подходит как для обучения и сравнения различных ML-моделей, так и для прямого анализа экспериментальных данных.

Identifying Dynamic Metal–Ligand Coordination Modes with Ensemble Learning
https://pubs.acs.org/doi/10.1021/jacs.5c17169
👉🏻Web interface enabling no-code prediction of ligand coordination modes: https://molsimplify.mit.edu/pydentate.html

In this work, we curate data sets of hemilabile and nonhemilabile ligands from experimentally characterized structures in the Cambridge Structural Database, analyze trends in observed coordination modes, and introduce four exhaustive and mutually exclusive types of hemilability.
Using these labeled data sets, we train graph neural networks to carry out classification of hemilabile ligands with high accuracy, precision, and recall and develop an ensemble algorithm that predicts primary and alternative chemically plausible coordination modes from SMILES strings in an end-to-end fashion. We demonstrate the utility of our algorithm by generating novel TMCs in predicted coordination modes and calculating the corresponding energy difference due to changes in coordination (i.e., ΔEc) with density functional theory.
Comparing our novel TMCs in multiple poses against an energetic criterion from experimentally observed TMCs confirms the plausibility of our alternative poses. We anticipate that our open-source workflows will accelerate organometallic discovery in experimental and virtual screening campaigns by proposing realistic metal–ligand coordination.

Identifying Dynamic Metal–Ligand Coordination Modes with Ensemble Learning
Knowledge of how a ligand coordinates a metal is essential for mechanistic and data-driven studies of transition metal complexes (TMCs), but most analyses assume a single binding interaction for a given metal–ligand pair. In catalysis, many ligands engage…

Сегодня хочется отойти от химии и поделиться свежей книгой по LLM на 250+ страниц:
This is a book about large language models. As indicated by the title, it primarily focuses on foundational concepts rather than comprehensive coverage of all cutting-edge technologies. The book is structured into five main chapters, each exploring a key area: pre-training, generative models, prompting, alignment, and inference. It is intended for college students, professionals, and practitioners in natural language processing and related fields, and can serve as a reference for anyone interested in large language models.

oMeBench: Towards Robust Benchmarking of LLMs in Organic Mechanism Elucidation and Reasoning 🔥
https://arxiv.org/abs/2510.07731
#benchmark
https://arxiv.org/abs/2510.07731
We address this by introducing oMeBench, the first large-scale, expert-curated benchmark for organic mechanism reasoning in organic chemistry. It comprises over 10,000 annotated mechanistic steps with intermediates, type labels, and difficulty ratings.
Furthermore, to evaluate LLM capability more precisely and enable fine-grained scoring, we propose oMeS, a dynamic evaluation framework that combines step-level logic and chemical similarity.
We analyze the performance of state-of-the-art LLMs, and our results show that although current models display promising chemical intuition, they struggle with correct and consistent multi-step reasoning. Notably, we find that using prompting strategy and fine-tuning a specialist model on our proposed dataset increases performance by 50% over the leading closed-source model.

Computer vision for high-throughput materials synthesis: a tutorial for experimentalists🔥
https://doi.org/10.1039/D5DD00384A
📕 Digital Discovery (IF=6.2)
#method
https://doi.org/10.1039/D5DD00384A
Here, we aim to fill that identified gap and present a structured tutorial for experimentalists to integrate computer vision into high-throughput materials research, providing a detailed roadmap from data collection to model validation.
Specifically, we describe the hardware and software stack required for deploying CV in materials characterization, including image acquisition, annotation strategies, model training, and performance evaluation.
As a case study, we demonstrate the implementation of a CV workflow within a high-throughput materials synthesis and characterization platform to investigate the crystallization of metal–organic frameworks (MOFs). By outlining key challenges and best practices, this tutorial aims to equip chemists and materials scientists with the necessary tools to harness CV for accelerating materials discovery.
