在阴离子二嵌段共聚物胶束存在下，在 25 摄氏度的水中，通过可见光引发阳离子单体的 RAFT 聚合，实现了多室聚离子复合物 (PIC) 系统的可扩展合成。这种聚合诱导的分层静电自组装（分层 PIESA）通过可编程自组装实现结构分层，形成 多室 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层 PIESA 中发挥着决定性作用，以访问生物学相关但无法访问的多室 PIC 系统。
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 degrees 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.
