Abstract
The surface‐assisted alignment of a nematic liquid crystal yields a persistent ordered structure upon cationic photopolymerization of liquid‐crystalline epoxides. Linearly polarized light irradiation of a photocrosslinkable polymer containing azobenzene moieties played a crucial role in this procedure since the photoinduced alignment is not deteriorated by heating for polymerization.
