Binary cocrystals, formed through π-π stacking, charge transfer, and hydrogen/halogen bonding, allow for precise control over molecular packing and enhanced optoelectronic properties. In contrast, higher-order cocrystals, incorporating three or more components, enable greater complexity and functional diversity. Strategies such as homologation via isostructural substitution, hierarchical intermolecular interactions, and long-range Synthon Aufbau Modules facilitate the synthesis of these advanced materials. The shift toward higher-order cocrystals paves the way for novel applications in fields such as deep learning for cocrystal prediction, drug design, organic solar cells, and NIR-II photothermal conversion. However, challenges related to molecular screening, ratio optimization, scalable synthesis, and long-term stability remain critical hurdles for the broader implementation of these materials in practical applications.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"137 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional polymer and thin-film emitters often face efficiency losses at long wavelengths and limited operational stability. Organic molecular crystals have emerged as promising alternatives by offering high purity, low defect density, and unique optical anisotropy. Among them, red-emissive organic molecular crystals (ROMCs) remain relatively underdeveloped compared to their blue and green counterparts. Moreover, the inherent brittleness of most crystals poses significant challenges for their integration into flexible and wearable devices. This review highlights recent advances in the design and development of ROMCs, emphasizing molecular and crystal engineering strategies to overcome photophysical limitations and impart mechanical flexibility. Emerging applications in organic lasers, optical waveguides, and bioimaging are discussed, alongside key challenges and future research directions. By bridging fundamental understanding and practical deployment, this perspective offers a comprehensive roadmap for the rational design of flexible, red-light-emitting crystalline materials for next-generation optoelectronic platforms.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"137 28","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144573549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A long shelf life of the perovskite precursor could greatly benefit the reliable upscaling of perovskite solar cells (PSCs). Herein, we suggest that the most commonly used N, N-Dimethylformamide/Dimethyl sulfoxide (DMF/DMSO) mixed solvent exhibits more severe degradation compared to its corresponding single solvents, due to the complex interplay of reactions, including hydrolysis, oxidation, and deprotonation of precursor species in the solution. 2-thiouracil (Th) was thus introduced into the precursor to inhibit these side reaction chains and effectively alleviate the detrimental degradation of cations and iodide ions (I⁻). The synergistic effects of Th allow it to bind with undercoordinated Pb2+, modulating the crystallization process and thereby achieving high-quality films with a low defect density. Consequently, Th-based precursor demonstrates enhanced shelf life, retaining 94.78% of the initial efficiency (25.13%) of the device prepared from fresh solution after 30 days of aging, compared to 64.22% for the control sample. The target device also exhibits remarkable stability, maintaining 87.8% of its initial efficiency after 1000 h of maximum power point tracking.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"137 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144624470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Guided by steady-state emission measurements with 800 nm excitation, the authors suggested that the underlying mechanism for the generation of the photoexcited key species is a simultaneous two-photon absorption via a virtual state. However, such a mechanism requires pulsed laser excitation and cannot compete when a conventional one-photon excitation is also feasible with the selected excitation wavelength range. Using several spectroscopic techniques and reactivity assays under different light color and intensity conditions, we unambiguously demonstrate that a conventional one-photon excitation followed by rather inefficient singlet oxygen generation (quantum yield <5%) is responsible for the observed photoreactivity of the Cu(I) complex. In addition, we briefly summarize general mechanistic considerations, estimate typical photon densities required for a variety of two-photon mechanisms, highlight the importance of optical filters and impurities to avoid artifacts in the emission spectra, and present some guidelines for the differentiation between one- and two-photon mechanisms.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"137 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144339145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
