经多步反应合成2种新型含希夫碱侧基聚酯(P5,P6),进一步与醋酸锌反应得到2种聚酯锌配合物(P5-Zn,P6-Zn).采用元素分析、FT-IR、UV-Vis、1H NMR、GPC、TG、DSC和荧光光谱等技术手段对其结构和性能进行表征.P5和P6均溶于四氢呋喃(THF)、氯仿(CHCl3)、N,N-二甲基甲酰胺(DMF)、N,N-二甲基乙酰胺(DMAc)、二甲基亚砜(DMSO)、N-甲基吡咯烷酮法(NMP)等有机溶剂,P5-Zn和P6-Zn部分溶于THF及CHCl3,溶于DMF、DMAc、DMSO、NMP等有机溶剂.P5和P6的重均相对分子质量Mw及相对分子质量分布指数PDI分别为4164、6148 g/mol和1.42、1.43.P5、P6、P5-Zn和P6-Zn的5%失重温度分别为339、348、367和358℃.P5、P6、P5-Zn和P6-Zn的玻璃化转变温度Tg分别为88.8、123.3、39.8和63.8 ℃.P5和P6的DMF溶液(5×10-5 mol/L)在418和416 nm处发射弱紫色荧光,P5-Zn和P6-Zn的DMF溶液(5×10-5 mol/L)在505和506 nm处发射强绿色荧光,固体P5-Zn和P6-Zn在527和532 nm处发射强绿色荧光.
