新型聚席夫碱及镍配合物的制备与发光性能研究

摘要

Two aromatic Schiff base polymer was synthesized by means of polymer condensation reaction using dimethyl terephthalate and 1,4-phthalaldehyde as raw material respectively. The corresponding com-plex was prepared by using the two kinds of polyschiff base as ligand complex divalent nickel. The micro-structure of the ligand and complexes were characterized by FTIR and UV,the luminescence properties of the complexes were characterized by luminescent spectra. The results show that,when irradiated with the maximum excitation wavelength,two kinds of polyschiff base nickel complexes emit spectral lines of 491 nm and 495 nm,is a potential luminescent material.%分别以对苯二甲酸二甲酯、对苯二甲醛和水合肼为原料，采用聚合物缩合法合成两种新型的芳香族席夫碱聚合物，以两种席夫碱聚合物作为配体与二价镍进行络合反应制备出相应配合物，并采用红外光谱和紫外光谱测试方法对所制备的配体和配合物的微观结构进行表征，同时利用荧光光谱对两种聚席夫碱-镍配合物的光学性能进行初步研究。结果表明，经最大激发波长激发时，两种聚席夫碱-镍配合物分别发射出491 nm和495 nm的谱线，是一种潜在的发光材料。
