摘要
在以CuCl和四甲基乙二胺(TMEDA)作为催化剂和邻二氯苯作溶剂条件下,以二-(4-乙炔苯基)-4-辛氧基苯胺(M1)和3, 6-双(乙炔基)-N-辛基咔唑(M2)作为单体,通过Glaser-Hay氧化偶联反应合成了含有咔唑和三苯胺结构单元的聚芳烃二乙炔共轭聚合物.采用红外光谱、核磁共振谱、热失重分析、紫外吸收光谱和荧光光谱等方法对聚合物进行结构表征与性能测试.所得到的聚合物都溶于普通的有机溶剂(如四氢呋喃、二氯甲烷、氯仿、甲苯等).结果表明,聚合物具有优异的热稳定性,热失重5 %时,分解温度在400℃以上;在光激发的条件下,聚合物在二氯甲烷溶液中发射蓝光.
Novel conjugated polymer containing diacetylenes was synthesized by CuCl-catalyzed oxidative coupling of aromatic diynes. The structures and properties of the polymers were characterized and evaluated by IR, NMR, TGA, UV, and photoluminescence （PL） analyses. All the polymers are completely soluble in common solvents such as toluene, THF, chloroform, and dichloromethane. These polymers possess good thermal stability and emit strong blue Tight near 450 nm.
