用8-羟基喹啉在有相转移催化剂存在的碱性条件下,与氯仿作用合成5-甲酰基-8-羟基喹啉,然后将5-甲酰基-8-羟基喹啉分别与对苯二胺、联苯二胺,4,4’-二氨基二苯砜反应,得到三种双-8-羟基喹啉-席夫碱配体,然后与金属离子配位,得到了一类新型的双-8-羟基喹啉-席夫碱-金属高分子配合物,再结合双-8-羟基喹啉-席夫碱配体与其它离子的显色反应,进行对比分析。利用红外光谱、紫外光谱对配体和配合物的结构进行表征,利用荧光光谱研究了高分子配合物的光致发光性能。
5-formyl-8-hydroxyquinoline was synthesized by the reaction of 8-hydroxyquinoline with chloroform in the presence of a phase transfer catalyst under alkaline conditions, and then 5-formyl-8-hydroxyquinoline was reacted with p- Amine, biphenylenediamine and 4,4’-diaminodiphenyl sulfone. Three kinds of bis-8-hydroxyquinoline-Schiff base ligands were obtained and coordinated with metal ions to obtain a new type of bis 8-hydroxyquinoline-Schiff base-metal complexes, and then with the color reaction of bis-8-hydroxyquinoline-Schiff base ligand with other ions, comparative analysis. The structures of the ligands and complexes were characterized by infrared spectroscopy and ultraviolet spectroscopy, and the photoluminescence properties of the polymer complexes were studied by fluorescence spectroscopy.
