利用Suzuki偶合反應將含尿素基團分子與茀合成高分子，並探討其螢光性質

Abstract

主要合成以imidazolidin-2-one為起始物，在1,3-N,N’的位置上接上對-溴苯基，再和茀的雙硼酯進行Suzuki-Miyamura偶合反應，形成以茀為主體的共聚合物。其中摻雜了茀、cabazole以及三苯胺的溴化物，並各依不同比例來和含尿素基團的溴化物搭配，再和茀的雙硼酯進行Suzuki-Miyamura偶合反應來得到共聚合物。並探討這些共聚合物溶液態與薄膜態的紫外-可見光吸收光譜和螢光放射光譜以及熱分析等性質。

In my study, we use imidazolidin-2-one as starting material to couple with para-bromophenyl on 1, 3-N,N’ position, and after that, we couple with fluorene by Suzuki- Miyamura reaction to forming fluorene-based polymers. We also report the preparation of polymers that are copolymerization of fluorene, cabazole or tripheny- amine and cyclic urea. The substituent effects on the photophysical and thermo properties of these copolymers have been carefully explored.
