摘　　要：利用德布斯(Debus)法合成了两种不同结构的二溴洛粉碱,以它们为单体分别与2,5-二壬氧基-1,4-二乙炔基苯偶联聚合,得到两种链节中含有三苯基咪唑结构单元的洛粉碱共轭聚合物。对单体和聚合物进行了结构表征并初步测试了两种共轭聚合物的紫外-可见吸收和荧光性能。In this paper,two dibromo-lophines of different structures were synthesized by Debus method and coupled with 2,5-dinonyoxy-1,4-diacetylenyl benzene as monomers,so as to obtain two kinds of lophine conjugated polymers containing triphenyl imidazole structural units.The structures of monomer and polymer were characterized,and the UV-vis absorption and fluorescence properties of the two conjugated polymers were preliminarily tested.
