Abstract

Twenty chitosan derivatives with systematic variations in their chemical functionalities were prepared, by grafting phthaloyl groups, various cinnamoyl derivatives, and poly(ethylene oxide) moieties onto the chitosan backbones and then their self-assembled architectures were investigated. Derivatives with a high level of 2,4,5-trimethoxycinnamoyl substitution gave rod-shape and/or planar-shape architectures through solvent displacement, whilst the other derivatives gave spheres. Transformation of self-assembled architectures was also observed in derivative with an appropriate level of 2,4,5-trimethoxycinnamoyl substitution.
