摘　　要：本文以各种桥联双水杨醛与不同的二胺反应合成一系列聚Salen配体及其相应的锌(Ⅱ)配合物。通过核磁共振、红外光谱确定物质的化学结构;利用紫外吸收光谱和荧光发射光谱研究它们的发光性能,并计算物质的荧光量子效率为:0.71%~1.65%;热重分析测得锌(Ⅱ)配合物的热分解温度高于400℃,具有较好的热稳定性;循环伏安法确定其能级带隙约为2.32~2.95 eV。通过分子设计可以改变材料的发光波长、荧光量子效率、热稳定性等性能。A series of poly - salen ligands derived from aliphatic or aromatic diamine with bridged disalicyclalde- hyde and corresponding zinc （Ⅱ） - chelate complexes were designed and synthesized successfully. The chemical struc- tures of the complexes were characterized by 1H NMR, 13C NMR spectra and IR spectra; and the luminescence prop- erties of the complexes were characterized by UV- Vis absorption spectra, fluorescence spectra. The fluorescence quantum efficiency of the complexes was 0.71% ~ 1.65%. The thermogravitometric analysis showed that the decom- position temperature of the zinc （Ⅱ） complexes were around 400 ℃. Cyclic voltammetry revealed that Energy band gap was 2.32 ~ 2.95 eV. Kinds of substitutes were introduced into the ligands to change emissive wavelengths, fluo- rescent quantum efficiency and thermally stable of the resulted complexes.
