摘要: Abstract A new poly( p -phenyleneethynylene) type polymer consisting of an electron-accepting 2,1,3-benzothiadiazole unit was prepared by polycondensation between 4,7-di(4-bromophenyl)-2,1,3-benzothiadiazole and 1,4-didodecyloxy-2,5-diethynylbenzene using Pd(PPh 3 ) 4 CuI as the catalyst. The soluble in chloroform showed photoluminescence solutions solid state. quantum yield considerably enhanced introduction two -phenylene units at unit. electrochemically active had good heat resistance.
