Scalable synthesis of multicompartment polyion complex (PIC) systems has been achieved via visible light-initiated RAFT polymerization of cationic monomer in the presence of anionic diblock copolymer micelles in water at 25 °C. This polymerization-induced hierarchical electrostatic self-assembly (hierarchical PIESA) implements structural hierarchy via programmable self-assembly to form multicompartment PIC micelles and their monolayer colloidal nanosheets and nanocages. The anionic micelles play decisive roles in such a hierarchical PIESA to access biologically relevant yet otherwise inaccessible multicompartment PIC systems.
通过在25℃下于水中阴离子二嵌段共聚物胶束存在的情况下，对阳离子单体进行可见光引发的可逆加成-断裂链转移（RAFT）聚合，实现了多隔室聚离子复合物（PIC）体系的可扩展合成。这种聚合诱导的分级静电自组装（分级PIESA）通过可编程自组装实现结构分级，以形成多隔室PIC胶束及其单层胶体纳米片和纳米笼。阴离子胶束在这种分级PIESA中起着决定性作用，以获得具有生物学相关性但难以获得的多隔室PIC体系。
