以N,N′-二氯对苯醌二亚胺、N,N′-二氯-2,5-二甲基对苯醌二亚胺与N-丁基-2,5-二溴吡咯的格氏试剂通过二价镍配合物催化法合成了相应的交替共聚物,PNBuPAN和PNBuPDMAN,上述两种聚合物的产率分别为56.8%,52.6%。利用红外光谱、紫外-可见吸收光谱、循环伏安、凝胶色谱(GPC)等对所得聚合物的基本性能和分子量等进行了表征。聚合物在二甲基甲酰胺中的紫外-可见最大吸收波长分别在451 nm和455 nm处出现。所得聚合物在本征态时基本为绝缘体,而经碘掺杂后则具有了一定的电导率,分别为1.51×10-6S/cm和3.89×10-6S/cm。通过电化学测试得知经碘掺杂以后两种聚合物的电化学活性均有明显的提高。
N, N’-dichloro p-benzoquinone diimine, N, N’-dichloro-2,5-dimethyl p-benzoquinone diimine and N-butyl-2,5-dibromopyrrole Grignard reagents were synthesized by the nickel-catalyzed synthesis of the corresponding alternating copolymer, PNBuPAN and PNBuPDMAN, the yield of the two polymers were 56.8%, 52.6%. The properties and molecular weights of the obtained polymers were characterized by IR, UV-Vis, cyclic voltammetry and gel permeation chromatography (GPC). The UV-visible maximum absorption wavelength of the polymer in dimethylformamide appeared at 451 nm and 455 nm, respectively. The obtained polymer is basically an insulator in the eigenstate and has a certain conductivity after doping with iodine, which are respectively 1.51 × 10 -6 S / cm and 3.89 × 10 -6 S / cm. Electrochemical tests showed that the electrochemical activity of both polymers was significantly improved after iodine doping.
