摘要
通过1，1’-二甲酰氯二茂铁与双（8-羟基喹啉）联苯胺席夫碱的缩聚反应，得到了二茂铁-8-羟基喹啉型缩聚物，然后与不同的金属离子配位，获得了一类新型的二茂铁8-羟基喹啉型高分子金属配位聚合物。用红外光谱（IR）、元素分析、差热分析（DSC—TGA）、荧光光谱对配体和金属配位聚合物进行表征。结果表明，配住金属参与后，提高了缩聚物的热性能。配体和配聚物的荧光性能分析表明，化舍物的发射谱出现在425～550nm之间，并且呈现三重荧光性质，在配体与金属离子配合后，其荧光强度增强。
A novel compound of Dis（8-hydroxyquinoline schiff base） containing ferrocenyl group was prepared by polycondensation between 4,4r-biphenyl-diamine Dis（8-hydroxyquinoline schiff base） and 1, 1＇-dichroloformyl- ferrocene. Then metal （Co, Ni, Cu）-coordinated polymers containing ferrocenyl group and 8-hydroxyquinoline were obtained by self-assembly property. Its properties of ligand and metal-coordinated polymers were characterized by infrared absorption spectroscopy （IR）, elemental analysis, thermal analysis （TGA） and fluorescence spectra. The result indicated that it was just the objects we wanted ; its thermal analysis showed that the stability of metal-coordinated polymers had better improvement compared with that of ligand. The emission fluorescence spectra of all the compounds ranged from 425nm to 550nm when excited by the light of maximal excitation wavelength（390nm） at the room temperature; ligand and metal-coordinated polymers exhibited stronger solid tripartite-peaks fluorescence properties; the fluorescence intensity of metal-coordinated polymers had got better improvement compared with that of ligand.
