Synthesis and Characterization of Copolymers Consisting 2, 5-Dimethyl N,N′-p-Benzoquinonediimine and Alkoxy Benzene

Using nickel(Ⅱ) complex as catalyst, three type of copolymers which consisting 2,5-dimethyl N, N′-p benzoquinonediimine and Grignard reagent of iodo alkoxy benzene with different carbon atoms were synthesized by metal complexes catalyzed polymerization. These copolymers were characterized by FT-IR, 1H-NMR, UV-Vis, cyclic voltammogram (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 copolymers 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°.
