Photoinduced reversible transmittance modulation of rod-coil type diblock copolymers containing azobenzene in the main chain

Abstract

Photoinduced reversible transmittance modulation was achieved with the self-assembled block copolymer micelles. A large conformational change of the well-defined rod-coil diblock copolymers containing azobenzene and ether groups in the main chain of the rod block induced a remarkable macroscopic change which can be observed with the naked eye.
