摘　　要：通过金属配合物催化法,在1,3-双(二苯基膦)丙烷二氯化镍(Ⅱ)存在的条件下,合成了2,5-二甲基对苯醌二亚胺与不同碳数的碘代烷氧基苯的3种共聚物。通过FT-IR、1 H-NMR、UV-Vis、循环伏安(CV)、XRD和凝胶渗透色谱(GPC)等测试手段对其进行了表征。结果表明:3种共聚物在三氟乙酸(TFA)溶液中的紫外可见最大吸收波长分别在517、576、651nm处;该类共聚物均在-0.2～0.8V出现两对氧化还原峰;共聚物的规整度较高,衍射峰的位置在19.6°～23.5°。Using nickel（ Ⅱ ） complex as catalyst, three type of copolymers which consisting 2,5-dimethyl- N, N1-p-benzoquinonediimine and Grignard reagent of iodo-alkoxy benzene with different carbon atoms were synthesized by metal comp FT-IR, 1H-NMR, UV-Vis, cycl exes catalyzed polymerization. These copolymers were characterized by c vohammogram （CV）, XRD and GPC. Results show that the maximum UV-Vis absorption of these polymers appear at 517, 576, 651 nm in CF3COOH, respectively. The copoly- mers have two redox peaks in the range from -0.2 V to 0.8 V. The figures of copolymers have well cry- stallized, and the diffraction peaks in the range of 19.6°-23.5°.
