摘　　要：以联苯二胺及二甲基联苯二胺为原料,合成了相应的N,N′-二氯联苯醌胺单体,并以二价镍配合物为催化剂与二连噻吩共聚得到了相应的交替共聚物。所得聚合物通过FT-IR,1H-NMR进行了表征。所得聚合物紫外-可见光谱分别在330、437、327、410nm处最大吸收峰出现。所得聚合物在-0.1～0.8V之间进行循环伏安分析,每一个聚合物都观察到两对氧化峰和还原峰分别在(Epa=0.40V/Epc=0.31V和Epa=0.70V/Epc=0.56V)和(Epa=0.33V/Epc=0.28V和Epa=0.63V/Epc=0.50V)。Two new alternative -conjugated copolymers were synthesized by nickel （Ⅱ） complex catalyzed polycondensation of N,N′-dichlorodiphenoquinone diimine or 3,3′-dimethyl-N,N′-dichlorodiphenoquinone diimine with 5,5′-dibromo-2,2′-bithiophene.The monomers were prepared from corresponding benzidines.The copolymers were characterized by UV-Vis,FT-IR,1H NMR and cyclic voltammogram.The copolymer Ⅰ （in DMSO） showed two Absorption peaks at about 330 and 437nm,respectively,while copolymer Ⅱ showed two Absorption peaks at about 327 and 410nm,respectively.The results from cyclic voltammogram in the range of -0.1-0.8V showed that each polymer had two symmetric reduction and oxidation peak in which Epa=0.40V/Epc=0.31V and Epa=0.70V/Epc=0.56V for copolymer Ⅰ,and Epa=0.33V/Epc=0.28V and Epa=0.63V/Epc=0.50V for copolymer Ⅱ,respectively.
