以二价镍配合物(Ni(dppp) Cl2)作为催化剂,2-二异丙基氨基-4,6-二氯均三嗪分别与3-丁基-2,5-二溴噻吩格氏(Grignard)试剂、3-辛基2,5-二溴噻吩格氏试剂、3-十二烷基-2,5-二溴噻吩格氏试剂交替共聚合成了3种含2-二异丙基氨基均三嗪的聚合物P1,P2和P3.并经傅里叶变换红外光谱、氢核磁共振谱、紫外-可见光谱、荧光光谱、循环伏安、X射线粉末衍射和凝胶渗透色谱等测试手段对其进行了表征,对聚合物P1在CHCl3溶液中的酸致变色行为进行了研究.结果表明,得到的聚合物在甲苯、氯仿、四氢呋喃(THF)等有机溶剂中溶解性好,3种聚合物的紫外-可见最大吸收波长在372 nm处出现,在CHCl3溶液中聚合物P1,P2,P3最大发射峰分别位于478nm,549nm和523nm.聚合物均在-1.8～0 V出现n-掺杂峰.通过X射线衍射测试聚合物均有一定结晶性但结晶性较差.
