Multi-responsive nitrobenzene-based amphiphilic random copolymer assemblies.

A photo-, acid- and thermo-responsive nitrobenzene-based amphiphilic copolymer was synthesized and the corresponding multi-responsive behavior of the copolymer assemblies was revealed by TEM, DLS and AFM. The morphological changes of the assemblies under multi-stimuli endowed them with a controlled release of encapsulated molecules.
