## Abstract We have prepared photoresponsive oligomers that have molecular weights of ca. 4500, 8000, and 16 000 g mol^–1^ via the free‐radical polymerization of 4‐[4‐alkylphenylazo]phenoxyalkyl acrylates. All of the oligomers possess bilayer smectic A (SmA) and smectic B (SmB) phases. Increasing t
