Abstract

This paper describes the self-assembly of rod–coil inclusion complexes, polyethylenimine–poly(ethylene glycol)–α-cyclodextrin (PEI–PEG–α-CD). It is demonstrated that α-CDs should exclusively thread on the PEG block in PEI–PEG copolymers and the resulting complexes have both rigid block (PEG–α-CD) and coil block (protonated PEI). By varying the rigid block fraction, aggregates with hollow spheres or rod-like particles could be formed simply by self-assembly in aqueous solution.
