The SC* phase is induced by chiral dopants. Therefore, the chiral dopants strongly affect the phase behavior of the resulting ferroelectric liquid crystals(FLCs). In this study, we synthesized a photochromic chiral dopant containing an azobenzene moiety and investigated the FLC behavior of the mixture of the chiral dopant and host LC. We further explored the photochemical switching behavior of the mixture by steady-state and time-resolved measurement. We found that trans→cis photoisomerization of the chiral dopant effectively caused disappearance of the SC* phase and cis→trans back isomerization restored the SC* phase.
