利用标准Suzuki反应条件,通过双(4-溴苯基)富马氰和系列芳香族硼酸酯偶合,得到系列聚(2,3-二芳基富马氰).所获得的4种聚合物的合成收率均超过70%,数均分子量Mn为8400～140000;特性粘数[η]为0.31～0.77dLg-1(甲苯,30℃).聚合物溶于普通有机溶剂,具有良好的成膜性.4种聚合物的甲苯溶液显示相似的UV-vis光谱(λmax=413 nm).荧光光谱显示,甲苯溶液中,聚合物的最大发射波长在约544 nm处,荧光量子收率＞30%.聚合物薄膜的最大发射波长为560 nm.粉末X衍射显示,聚合物在2θ＜7°区产生较强的衍射峰,这些小角区的衍射峰所对应的烷氧基侧链间距d1和烷氧基侧链的碳原子数n显现良好的线性关系.热重分析(TGA)显示,氮气中,聚合物的5%重量损失温度＞340℃.电化学分析(CV)表明,在0.1 M支持电解质[Bu4N]BF4的乙腈溶液中,聚合物薄膜的氧化开始于0.68V(相对于Ag+/Ag电极),最大氧化峰值电位为1.03V;在0～-2.5V区域,聚合物的还原始于-1.34V,并在-1.65和-2.03V处给出两个峰值电位.相应的去还原电位为-1.67和-1.33 V.
