摘　　要：在钯催化下利用Heck耦合反应制备了以萘酰亚胺为发色团的共聚物,通过侧链上引入丁氧基醚链,使得聚合物具有很好的溶解度,能溶解在常用有机溶剂中.单体与聚合物结构均经1H NMR,FT-IR,并通过DSC和TGA分析表明聚合物具有较好的热稳定性,分解温度达到380℃.紫外,荧光测试表明聚合物具有较强的蓝色荧光,在光电分子传感器材料应用具有很大的发展潜力.Copolymers with the naphthoyimine chromophores were firstly obtained through Pdcatalyzed Heck reaction. The copolymers had good solubility in common solvents due to the presence of alkoxyl subs＇tituents in the molecular chains. Monomers and polymer both were characterized by ^1 H NMR,FT-IR and so on. According to DSC and TGA analysis, the copolymer possesses the better thermal stability with the decomposition temperature 380 ℃. UV-Vis and PL spectra results show that the polymer can emit very strong blue fluorescence, and they are expected to have potential application in the materials of electro-optical molecular sensors.
