Dendronized polystyrene having peripheral bromo groups was prepared from the dendronization of unfunctionalized polystyrene with dendritic diarylcarbenium ions bearing peripheral bromo groups using the "cation pool" method. The palladium-catalyzed amination of the peripheral bromo groups with diarylamine gave dendronized polystyrene equipped with peripheral triarylamines, which exhibited two sets of reversible redox peaks in the cyclic voltammetry curves.

具有外围溴基团的树枝状聚苯乙烯是通过使用“阳离子池”法，用带有外围溴基团的树枝状二芳基碳鎓离子对未官能化的聚苯乙烯进行树枝化反应制备的。用二芳基胺进行钯催化的外围溴基团的氨化反应，得到了带有外围三芳基胺的树枝状聚苯乙烯，其在循环伏安曲线上显示出两组可逆的氧化还原峰。
