Synthesis and Characterization of Alternating Copolymers Consisting of N-(nButy1)Pyrrole and p-Phenylenediamine

Using Ni(Ⅱ) complexes catalyzed method,two types of alternating polymers,which coupled separately by N,N′-dichloro-benzoquinonediimine and 2,5-dimethylN,N′-dichloro-benzoquinonediimine with Grignard reagents of N-(n-butyl)-2,5-dibromopyrrole,PNBuPAN and PNBuPDMAN,were successfully obtained.The yields of the above-mentioned copolymers were 56.8% and 52.6%,respectively.The basic properties and the molecular weights of the obtained copolymers were characterized by Fourier transform infrared spectrum(FT-IR),UV-Vis absorption, cyclic voltammetry and gel permeation chromatography(GPC) analyses.The absorption maxima of PNBuPAN and PNBuPDMAN appeared at 451 nm and 455 nm in N,N-dimethyllformamide(DMF),respectively.These two polymers were almost insulators in their eigenstate.After doped by iodine,the copolymers have certain conductivity, with 1.51×10-6S/cm for PNBuPAN and 3.89×10-6 S/cm for PNBuPDMAN,respectively.The electrochemical activity of iodine-doped polymers also is greatly improved as compared to the un-doped precursors.
