## 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
A sharp change in transmittance from a transparent state to a light scattering one within a tiny temperature range is induced accompanied with the heat-induced phase transition from a smectic-A (S A ) phase to a chiral nematic (N\*) one in a sidechain smectic-A liquid crystalline polymer ( S A LCP)
