二茂铁基聚乙烯亚胺的制备及其电化学行为

Preparation and Electrochemical Behaviors of Ferrocenyl Poly(ethylenimine)

通过N-烷基化反应将二茂铁十一烷基接枝到聚乙烯亚胺上,制备了一种新型的氧化还原型聚合物——二茂铁基聚乙烯亚胺(4),其结构经UV-Vis和13C NMR表征。用循环伏安法研究了4在二氯乙烷中的基本电化学行为,结果表明,4具有良好的氧化还原可逆性,是由扩散控制的准可逆过程。

A novel redox-active polymer, ferrocenyl poly （ ethylenimine ） （ 4 ）, was synthesized by grafting alkyl ferrocene on poly（ethylenimine） through N-alkylation reaction. The structure was characterized by UV-Vis and ^13C NMR. The basic electrochemical behavior in dichloroethane solution was also studied by cyclic voltammogram. The experimental results showed that 4 had a good redox reversibility, which was a diffusion controlled quasi-reversible process.
