Liquid crystalline copolymers containing 4'-cyanobiphenyl-4-oxyundecylacrylate (CBO-1 I-A) groups and phenylazophenyloxy-undecylacrylate (ABO-I I-A) groups with various proportions were synthesized. The copolymers take a highly liquid crystalline state but the temperature range of liquid crystalline
## Abstract We have prepared photoresponsive oligomers that have molecular weights of ca. 4500, 8000, and 16β000βgβmol^β1^ via the freeβradical polymerization of 4β[4βalkylphenylazo]phenoxyalkyl acrylates. All of the oligomers possess bilayer smectic A (SmA) and smectic B (SmB) phases. Increasing t
