摘　　要：以PdCl2(PPh3)2/CuI为催化剂,分别通过N,N′-二氯联苯醌二亚胺和3,3′-二甲基-N,N'-二氯联苯醌二亚胺与1,4-二炔基-2,5-二癸氧基苯共聚,得到共轭聚合物聚[联苯醌二亚胺-co-2,5-二癸氧基-1,4-苯撑乙炔](PBz-PPE)和聚[3,3′-二甲基联苯醌二亚胺-co-2,5-二癸氧基-1,4-苯撑乙炔](PDMBz-PPE)。采用红外光谱(FT-IR)、核磁共振(1H-NMR)、凝胶渗透色谱(GPC)、紫外-可见光谱仪(UV-Vis)等测试手段对共聚物的化学结构和性能进行表征。结果表明,在四氢呋喃和三氟乙酸溶液中,此类共聚物的紫外-可见最大吸收峰分别为410 nm和540 nm;在四氢呋喃中荧光发射峰均为485 nm;相对分子质量均在10000左右;通过循环伏安测试得知,本征态的2种共聚物均有1对氧化还原峰(分别为Epa=0.51 V,Epc=0.41 V和Epa=0.48 V,Epc=0.30 V),经碘掺杂以后2种共聚物的电化学活性均有明显提高,且有2对氧化还原峰。Under the presence of metal complex, poly（biphenyl quinone diimine-co-1,4-diethynyl-2,5-his （.n- decyloxy） benzene （PBz-PPE and PDMBz-PPE） was synthesized via cross coupling between the biphenyl quinone diimine and 1,4-diethynyl-2,5-bis（n-decyloxy） benzene. The copolymers were characterized by FT-IR, 1H-NMR, GPC, UV-Vis, photoluminescence （PL）and cycling voltammetry （CV）. The results show that UV-Vis maximum absorption wavelength of PBz-PPE and PDMBz-PPE in tetrahydrofuran （THF） is 410 nm, and in trifluoroacetic acid （TFA） is about 540 nm. The photoluminescence emission peak is about 485 nm. Molecular weight is about 10000. The result of cyclic voltammetry shows that PBz-PPE and PDMBz-PPE has one redox peaks at Epa = 0.51 V, Epc = 0.41 V and Epc = 0.48 V, Epc = 0.30 V respectively; after the iodine doped, the electrochemical activity of two kinds 6f copolymers is obviously improved, and them have two pairs of redox peaks.
