摘要

合成了一种希夫碱有机金属配合物2-羟基-1-萘甲醛缩邻苯二胺合锌(ZnL)。通过质谱、元素分析、红外光谱、热重分析对其结构进行了表征;利用紫外-可见光吸收光谱、激发和发射光谱研究了该配合物的光物理性能。结果表明:ZnL的热分解温度为433.2 ℃

具有很好的热稳定性;在DMF溶液体系中

配合物ZnL的紫外吸收带位于250~500 nm

荧光激发带位于343~493 nm

在紫外光的激发下发射峰在626 nm处

为橙红色光

最佳激发波长为470 nm

禁带宽度2.32 eV。

Abstract

A ligand on Schiff base

N'-bis(2-hydroxy-1-naphthylidene)-o-phenylenediamine

and its zinc complexes were synthesized. Its structure was investigated by MS

elemental analysis

FTIR spectra

TG-DTG curve; through UV-Vis absorption spectroscopy

fluorescence excitation and emission spectra the photophysical properties of the complexes were studied. The results showed that the ZnL's thermal decomposition temperature was 433.2 ℃

with very good thermal stability; in DMF solution system

the UV absorption band of ZnL complex was in the ranges of 250~500 nm

with fluorescence excitation in the ranges of 343~493 nm. The orange-red fluorescence emission peak wavelength was at 626 nm

the best excitation wavelength was 470 nm

and the band gap was 2.32 eV.
