In this context, a two-dimensional (2D) Co-based metal-organic framework SDU-CP- was rationally designed with 4-(4-carboxyphenyl)-1,2,4-triazole (Hcpt) and 2,4,6-tri(4-pyridinyl)-1,3,5-triazine (tpt) as organic linkers. The SDU-CP- was comprehensively characterized using single-crystal X-ray diffraction analysis, thermogravimetric analysis, fourier transform infrared spectroscopy, raman spectroscopy, powder x-ray diffraction analysis and UV-vis spectroscopy. Molecular docking were conducted to elucidate potential binding sites on SDU-CP- for effective interactions with RhB and ST. Featuring negatively charged surface and trigonal microporous channels, SDU-CP- exhibits excellent adsorption capacities of organic dyes (919.2 mg/g for Rhodamine B and 1565 mg/g for Safranine T) as well as iodine (563.0 mg/g in solution and 1100 mg/g in the vapor phase). The exceptional adsorption performance of SDU-CP- for cationic dyes can be ascribed to the electrostatic interaction facilitated by negatively charged zeta potential and the size-matching principle, whereas the pyridine active sites in channels significantly enhance the binding affinity for iodine. Moreover, SDU-CP- can serve as chromatographic column filters for the rapid adsorption and separation of dyes. The results demonstrate the excellent selective adsorption performance of SDU-CP-, highlighting its potential for environmental and industrial applications.","PeriodicalId":10151,"journal":{"name":"Chinese Journal of Structural Chemistry","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the change of molecular arrangement inside the crystal during solid-solid phase transition, the distortion of crystal lattice and the great change of lattice parameters are often caused, which result in a poor repeatability and short life. Thus, designing phase change materials with small lattice changes helps to improve product life. In this article, a novel organic-inorganic hybrid material 3HDMAPAPbBr4 (1, 3HDMAPA is 3-(hydroxydimethylammonio)propan-1-aminium) was successfully synthesized and characterized. For 1, organic cations filled in the van der Waals gap are connected by hydrogen bonds with halogens in the two-dimensional inorganic layer, forming a stable sandwich structure. During the solid-solid phase transition driven by temperature, the changes of inorganic skeleton are relatively small, and the disorder movement of organic cations does not affect the existence of hydrogen bonds, maintaining a relatively stable crystal structure. In addition, electrical property, optical property and crystal structures are analyzed and discussed in detail. We believe that our work will contribute to the development and application of phase change materials in response materials.</div></div>","PeriodicalId":10151,"journal":{"name":"Chinese Journal of Structural Chemistry","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of Cu28H10(SPhpOMe)18(DPPOE)3 and previously reported Cu28H10(SPhoMe)18(TPP)3 constructs a structure-correlated cluster pair with comparable structures and properties. Accordingly, the ligand effects in directing the geometric structures and physicochemical properties (including optical absorptions and catalytic activities towards the selected hydrogenation) of copper nanoclusters were analyzed.
