摘要：

This paper summarizes an effect of trans-cis photoisomerization of a chiral azobenzene compound on a phase structure of the compensated nematic liquid crystal (LC) consisting of the chiral azobenzene compound, nonphotochromic chiral compound with opposite twisting ability, and a host nematic LC. The trans-cis photoisomerization results in the reversible phase transition between the nematic and a cholesteric phases, resulting in a significant change in the transmittance of the sample.
