【摘要】 以1,1′-二甲酰氯二茂铁与双(8-羟基喹啉)联苯胺席夫碱为原料,通过缩聚反应得到了二茂铁- 8-羟基喹啉型缩聚物,再与不同金属离子(Co,Ni,Cu)配位,获得了一类新型的聚二茂铁-双(8-羟基喹啉)金属配合物.用红外光谱(IR)、元素分析、差热分析(DSC-TGA)、X射线衍射(XRD)及荧光光谱对金属配合物的结构与性能进行了研究.结果表明,配位金属参与后,提高了缩聚物的热性能.XRD研究表明配体与金属配合物均呈现短程有序的微晶态.配体和配聚物的荧光性能分析表明,化合物的发射谱出现在425-550 nm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.更多还原

【Abstract】 A novel compound of dis(8-hydroxyquinoline schiff base)containing ferrocenyl group is prepared by polycondensation of 4,4′-diphenyl-diamine dis(8-hydroxyquinoline schiff base)and 1,1′-dichroloformyl-ferrocene.Then metal(Co,Ni,Cu)-coordination polymers containing ferrocenyl group are obtained by self-assembly property.The structures and properties of metal-coordination polymers are characterized by IR,elemental analysis,TGA,XRD and fluorescence spectra.The result indicates that the thermal stability of metal-coordination polymers has been improved as compared with that of the ligand.X-ray diffraction shows the ligand and metal-coordination polymers take on microcrystalline with short-range order.The emission fluorescence spectra of all the compounds range from 425-550 nm.The ligand and metal-coordination polymers exhibit stronger triple-peaks fluorescence properties.The fluorescence intensity of metal-coordination polymers get better improvement compared with that of ligand.更多还原
