4,4'-二(苯并咪唑-1-甲基)联苯及樟脑酸构筑的二维镉配合物的合成、晶体结构及荧光性质

摘要

A 2D complex [Cd((bbmb)(CAM)]n, based on a semi-rigid N-containing ligand bbmb (bbmb=4,4'-bis (benzimidazol-l-ylmethyl)biphenyl) and H2CAM (H2CAM=camphoric acid) has been synthesized by hydrothermal method and characterized by IR spectra, elemental analysis, PXRD, TGA, and the crystal structure was determined by single-crystal X-ray diffraction. The complex crystallizes in the orthorhombic system, space group P212121, and features a two-dimensional (2D) layer structure. Second harmonic generation efficiency and fluorescence of the complex are also further investigated. The experimental results show that this complex has a second harmonic generation response and good fluorescence property, which can be used as a second-order nonlinear optical material and a potential fluorescence material. CCDC: 873460.%以4,4'-二(苯并咪唑-1-甲基)联苯和樟脑酸为配体,用水热法合成了1个二维镉配位聚合物[Cd(bbmb)(CAM)]n(bbmb=4,4'-二(苯并咪唑-1-甲基)联苯,H2CAM=樟脑酸),对其进行了红外光谱、元素分析、粉末XRD和热重分析等表征,并用X-射线单晶衍射法测定了配合物的单晶结构.该配合物属正交晶系,P212121空间群,为二维层状结构.对其二次谐波产生效率和荧光性质进一步研究表明该配合物具有二级非线性光学效应和较好的荧光性,是潜在的二阶非线性光学材料和荧光光学材料.
