Photocleavable amphiphilic diblock copolymer with an azobenzene linkage

Author affiliations

Abstract

Amphiphilic diblock copolymers with an azobenzene linkage were synthesized by a macromolecular azo coupling reaction between a PEG based macromolecular diazonium salt and a PS based polymeric block with a functional terminus. Colloidal aggregates could be directly prepared by self-assembly of the prepared amphiphilic copolymer in selective solvents (THF/H2O). By irradiation with UV light, the azobenzene linkage in the block copolymer can be efficiently photocleaved. Thus, the colloidal aggregates of the amphiphilic diblock copolymer will be disrupted due to the cleavage of the azobenzene junction.
