DNA coacervates are micron-scale, membrane-free, spherical structures formed by liquid-liquid phase separation of DNA materials. They uniquely combine the programmability of DNA with the fluidic properties of coacervates, allowing for controlled modulation of their structures, biomimetic and biological functions, and dynamic behaviors through rational sequence design. This review summarizes methods for the formation of different DNA coacervates and explores their extensive applications in biomimicry, biosensing and therapeutics. Limitations and prospects of DNA coacervates are also discussed.</p>\u0000 \u0000 <p>\u0000 </p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Key Scientists</h3>\u0000 \u0000 <p></p>\u0000 </section>\u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"43 12","pages":"1442-1462"},"PeriodicalIF":5.5,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we introduce the polar [NH(CH<sub>2</sub>SO<sub>3</sub>)<sub>2</sub>]<sup>2−</sup> dimer as a novel non-π-conjugated FBU, and synthesize the first NLO iminodimethanesulfonate crystal, namely Cs<sub>2</sub>NH(CH<sub>2</sub>SO<sub>3</sub>)<sub>2</sub>·H<sub>2</sub>O. Experimental results demonstrate that this crystal exhibits second-harmonic generation (SHG) responses with 0.8 times of KDP, moderate birefringence of 0.044@550 nm, and broad UV transparency (< 200 nm), enabling phase-matchable SHG at the key UV wavelength of 266 nm.

Through a comparative analysis of various machine learning algorithms and molecular fingerprints, we determined that the XGBoost algorithm, when combined with MACCS and Morgan fingerprints, exhibited superior performance. To further enhance predictive accuracy, we integrated chemical descriptors alongside multiple fingerprints, achieving an <i>R</i><sup>2</sup> value of 0.951 on the test set. The model demonstrated excellent generalization capabilities when applied to synthesized metal-trifluoromethyl compounds, highlighting the critical role of chemical descriptors in improving predictive performance. This research not only establishes a robust predictive model for metal-trifluoromethyl BDEs but also underscores the value of incorporating chemical insights into machine learning workflows to enhance the prediction of chemical properties.</p>\u0000 <p>\u0000 </p>\u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"43 12","pages":"1363-1372"},"PeriodicalIF":5.5,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
