Abstract

This article presents a study on the synthesis and character of a new organic-inorganic hybrid [4FBzTPP]₂[CuBr₄] (1) ([4FBzTPP]⁺ is 4-fluorobenzyltriphenylphosphinium) by XRD, SEM, FTIR and UV-Vis. The XRD analysis showed that the hybrid 1 belongs to the triclinic space group P2₁ with b = 8.8600(10) Å, c = 16.4867(17) Å, α = 16.639(2)°, β = 96.342(4)°, V = 2415.6(5) Å³, and Z = 2. The hybrid consists of two [4FBzTPP]⁺ cations and one [CuBr₄]^2– anion, and the [CuBr₄]^2– exhibits a twisted tetrahedral coordination geometry with the average bond length between Cu–Br is 2.393 Å. The 3D network structure of 1 is formed by electrostatic terms and other intermolecular interactions. The hybrid material undergoes a direct optical transition and has energy gap values of 1.66 eV and 2.18 eV, indicating its potential as a semiconductor material for optical research. The hybrid material undergoes a direct optical transition and has energy gap values of 1.66 eV and 2.18 eV, showing that the hybrid material is a potential semiconductor material for optical research. In addition, the compound exhibited good antibacterial activity against E. coli and S. aureus.

新型有机-无机杂化物 [4FBzTPP]2[CuBr4] 的合成、表征、晶体结构和抗菌特性

摘要本文通过XRD、扫描电镜、傅立叶变换红外光谱和紫外可见光谱研究了一种新型有机-无机杂化物[4FBzTPP]2[CuBr4]（1）（[4FBzTPP]+为4-氟苄基三苯基膦）的合成及其性质。XRD 分析表明，混合物 1 属于三菱空间群 P21，b=8.8600(10)埃，c=16.4867(17)埃，α=16.639(2)°，β=96.342(4)°，V=2415.6(5)埃3，Z=2。混合物由两个[4FBzTPP]+阳离子和一个[CuBr4]2-阴离子组成，[CuBr4]2-呈现扭曲的四面体配位几何结构，Cu-Br之间的平均键长为2.393埃。该杂化材料发生了直接光学转变，其能隙值分别为 1.66 eV 和 2.18 eV，这表明它具有作为半导体材料进行光学研究的潜力。该杂化材料发生了直接光学转变，其能隙值分别为 1.66 eV 和 2.18 eV，这表明该杂化材料有望成为一种用于光学研究的半导体材料。此外，该化合物对大肠杆菌和金黄色葡萄球菌具有良好的抗菌活性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
