合成了三种不同侧链封端基团的联吡啶聚合物PRV,其中R分别为乙基、正丁基和正壬基。循环伏安特性和紫外-可见光谱表明,其电化学活性的大小顺序为乙基>正丁基>正壬基;三者的电化学稳定性良好,其还原态均显示红紫色。
Three bipyridine polymers PRV with different side chain capping groups were synthesized, where R is ethyl, n-butyl and n-nonyl, respectively. Cyclic voltammetry and UV-Vis spectra showed that the order of their electrochemical activity was ethyl> n-butyl> n-nonyl. The electrochemical stability of the three compounds was good, and the redox state was observed in all the three samples.
