Three multinuclear metal-organic coordination compounds based on 8-hydroxyquinoline derivative: Syntheses, structures and fluorescence properties

By taking advantage of the synthetic 8-hydroxyquinoline derivative, (E)-242-(4-chlorophenyl)vinyl]-8-hydroxyquinoline (HL), three new metal-organic coordination compounds [Zn3L6] (1), [Cd3L6] (2) and [Cu2L4] (3) have been obtained by solvothermal or solution processing methods and structurally characterized. Single crystal X-ray diffraction analysis revealed that complexes 1 and 2 have similar trinuclear structures. Different from complexes 1 and 2 (trinuclear structure), complex 3 displays dinuclear structure. The effects of central metals and reaction solvents on the structures of complexes 1-3 have been discussed. Furthermore, thermogravimetric analysis and solid state fluorescence of ligand HL, 1-3 were investigated. (C) 2015 Elsevier Ltd. All rights reserved.

利用合成的8 - 羟基喹啉衍生物(E)-2 - [4 - (4 - 氯苯基)乙烯基]-8 - 羟基喹啉(HL)，通过溶剂热法或溶液法制备了三种新的金属 - 有机配位化合物[Zn₃L₆](1)、[Cd₃L₆](2)和[Cu₂L₄](3)，并对其进行了结构表征。单晶X射线衍射分析表明，配合物1和2具有相似的三核结构。与配合物1和2（三核结构）不同，配合物3呈现双核结构。讨论了中心金属和反应溶剂对配合物1 - 3结构的影响。此外，还研究了配体HL以及配合物1 - 3的热重分析和固态荧光性质。（C）2015爱思唯尔有限公司。保留所有权利。
