Abstract

original image

Light switch: Noncovalently connected micelles are formed by the photoisomerization of azobenzene groups in copolymer building blocks and the hydrogen-bonding interaction within the polymer pair. The UV-induced micellar structure can be fixed through core cross-linking, which allows the reversible optical switching of a micelle–hollow-sphere transition (see picture).
