一个对苯甲酸三联吡啶锌配合物的合成与荧光研究

Synthesis and Yellow Luminescence of A 4-carboxyphenylterpyridine Zinc Compound

用硝酸锌和4'-对苯甲酸-2,2',6',2″-三联吡啶(Htypb)合成了一种新的配合物[Zn(typb)_2](Htypb)_2(1),并对新化合物进行了X-射线单晶衍射、热重、红外、荧光等表征。化合物为零维结构,配体一部分与金属配位,另一部分游离。金属锌离子被两个三联吡啶基团螯合。标题化合物在325℃以下温度稳定存在。在波长424 nm光激发下,新化合物1在582 nm处有最大荧光发射,因此该物质是一种潜在的荧光材料。

A new compound 1,[Zn( typb)_2]( Htypb)_2,was synthesized from 4'-( 4-carboxyphenyl)-2,2',6',2″-terpyridine( Htypb) and Zn( NO_3)_2· 6H_2O, and it was characterized by X-ray single crystal diffraction,thermogravimetry analysis,infra-red spectrum,fluorescence spectrum,and so on. The new compound 1 was zero-dimnensional structure. Some of the organic ligands were coordinated with metal Zn^(2+),while the other ligands existed freely. Zn^(2+) was chelated by two terpyridyl groups. The title compound showed the maximum luminescence emission at582 nm under the excitation at 424 nm,which indicated that the new compound would be a potential luminescent material.
