Abstract

A block copolymer with diselenide bonds in the polymer backbone was reported. This block copolymer was capable of forming micellar aggregates that were responsive to redox stimuli. Compared with other redox responsive aggregates, this type of diselenide-containing block copolymer aggregates could be responsive to both oxidants and reductants even in a solution with a very low concentration under mild conditions.

摘要

据报道，有一种在聚合物主链中含有二硒键的嵌段共聚物。这种嵌段共聚物能够形成胶束聚集体，对氧化还原刺激有响应。与其他氧化还原响应的聚集体相比，即使在温和条件下、浓度非常低的溶液中，这种含有二硒键的嵌段共聚物聚集体也可以对氧化剂和还原剂都有响应。
