Two end-decorated homopolymers, poly (styrene)-β-cyclodextrin (PS-β-CD) and poly (ethylene oxide)-ferrocene (PEO-Fc), can orthogonally self-assemble into a supramolecular diblock copolymer (PS-β-CD/PEO-Fc) in aqueous solutions based on the terminal host− guest interactions. These assemblies can further form supramolecular vesicles, and their assembly and disassembly behaviors can be reversibly switched by voltage through the ...
