摘要

以双酚A 为原料合成了具有对称的桥联结构的双水杨醛

在此基础上合成了一系列的双希夫碱配体及相应的锌配位聚合物。利用红外吸收光谱、核磁共振等方法研究了化合物的分子结构

利用热重分析研究了配合物的热稳定性

利用紫外吸收、荧光光谱研究了该系列配合物的发光性能

利用循环伏安法测试了配合物的能级带隙。研究结果表明:该系列配合物具有较好的热稳定性

热分解温度为405~443 ℃;发光波长为493~503 nm

属于蓝绿光范围;量子效率和文献报道的相近;能级带隙约为3.04~3.23 eV。

Abstract

Four novel bis-Schiff base ligands and their zinc(Ⅱ) coordination polymers were synthesized from the bisalicylaldehydes based on the backbone of bisphenol A. The structures

thermal stabilities

luminescent properties and energy bands were investigated by infrared spectra

H NMR

TG curve

UV-Vis absorption spectra and fluorescence emission spectra. The results showed that these complexes are thermally stable with high decomposition temperature at 405 ~443 ℃. The complexes emit blue-green fluorescence with the maximum emission peaks at 493 ~503 nm. Their quantum yields are close to that of the repoted literatures

the band gap is about 3.04 ~3.23 eV. The results above suggest that the novel coordination ploymers can be utilized as good organic electroluminescent materials.
