photosensitive mesogens with lactate chiral units were synthesized. In order to modify the rate of the thermal Z–E isomerization of these compounds, small lateral substituents were introduced into their core in the proximity of the azo group. The influence of lateral substitution on the kinetics of the Z–E isomerization, mesomorphic behaviour, and UV-Vis absorption spectra was studied. It was found that
