For modern civilization development of efficient electronic devices is extremely helpful not only due to their technological aspect but also for their laboratory to land applications. Keeping in mind of the above issues, a copper(II)-based zigzag one dimensional coordination polymer [Cu(4-dpds)(4-cba)<sub>2</sub>]<sub>n</sub> (where 4-dpds represents 1,2-di(pyridine-4-yl)disulfane and 4-cba represents 4-chloro benzoate anion) has been synthesized and well-characterized through X-ray single crystal diffraction analysis, XPS analysis, SEM analysis, powder X-ray diffraction analysis, thermogravimetric analysis, absorption spectral analysis and infra-red spectral analysis. Structural characterization through single crystal X-ray diffraction analysis reveals that the zigzag wave like architecture has been generated due to the presence of S–S linked ligands (4-dpds) and strong hydrogen bonding interactions play pivotal role in the development of the supramolecular aggregate. Interestingly, the optical band-gap (2.15 eV) obtained from absorption spectra and the electrical conductivity at room temperature (measured as 9.73 × 10<sup>−4</sup> S cm<sup>−1</sup>) revealed the semiconducting nature of the coordination polymer. The theoretical calculation projected HOMO-LUMO energy gap (2.11 eV) and the Fermi level (near to valence band) estimated from DOS also justified the p-type behavior of the derived material. The device fabricated by sandwiching the coordination polymer in between ITO coated glass substrate and metallic aluminum, was observed to exhibit non-linear rectifying nature in current-voltage characteristic plot. Therefore, it is obvious that these kinds of easily synthesizable lower dimensional coordination polymers can be considered as potential candidates in the fabrication of Schottky like devices and also helpful for technological advancement as well as for the up-gradation of future research in the corresponding field.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"341 ","pages":"Article 125096"},"PeriodicalIF":3.2,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, it is crucial to distinguish their absolute conformations. Herein, a pair of chiral sensors, UiO-L-Pro and UiO-D-Pro, were obtained by immobilizing the chiral center <span>l</span>-proline (L-Pro) and <span>d</span>-proline (D-Pro) into a Zr-based metal−organic framework (MOF) via a condensation reaction. Fluorescence analyses revealed a notable difference in the enhancement of fluorescence intensity between UiO-L-Pro and UiO-D-Pro when treated with <span>l</span>-phenylalanine (L-Phe) or <span>d</span>-phenylalanine (D-Phe), demonstrating enantioselective luminescence properties. Differences based on hydrogen bond interaction give them significant enantioselectivity factors α. The enantioselectivity factors α (α = K<sub>BH</sub>(D-Phe)/K<sub>BH</sub>(L-Phe)) for UiO-L-Pro and UiO-D-Pro were 4.15 and 0.47, respectively. Thus, the chiral material could be employed to identify different configurations of phenylalanine.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"341 ","pages":"Article 125090"},"PeriodicalIF":3.2,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142593619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
