The trans to cis photoisomerization and cis to trans thermal isomerization of azobenzene derivatives molecularly dispersed in two types of polymer liquid crystals (PLCs), nematic and smectic PLCs, were investigated with reference to the inner free volume of the PLC matrices. The size distribution and the fluctuating nature of the inner free volume were examined, and it was found that the nematic phase posesses more inner free volume than the smectic phase.
