摘　　要：在室温和高速搅拌下,以十六烷基三甲基溴化铵为相转移催化剂,往咔唑和50％NaOH水溶液中缓慢滴加1,4-二氯-2-丁炔,反应24h后,经重结晶分离得到无色针状晶体。IR,~1H NMR,MS,VPO等结构分析方法确定无色针状晶体为反式N-3-炔丁烯基咔唑;加热生成的聚合物为聚炔烃,分子量为1.9×10~3,聚合度为9;通过DTA-TG分析和热聚合速率的测定,探讨了单体热聚合规律,测得热聚合活化能为118 kJ/mol。聚合物电导率小于10^(-12) S·cm^(-1),而与FeCl_3形成电荷转移络合物后则达到8×10^(-4)S·cm^(-1)。N-3-Yne-butenylcarbazole has been synthesized by stirring a mixture of carbazole, 1,4-dichloro-2-butyne, benzene, 50% NaOH and cetyl trimethyl ammonium bromide in water. The compound was polymerized by heating. The polymerization activated energy was 118 kJ/mol. Molecular weight of the polymer polymerized at 120 degreesC was 1.9 x 10(3) ( n approximate to 9). The conductance ratio of the polymer was less than 10(-12) S(.)cm(-1) and that of the charge transfer compound of the polymer with FeCl3 was 8 x 10(-4) S(.)cm(-1).
