Relationship between flexoelectricity and helical pitch in ferroelectric liquid crystal mixtures containing host achiral compounds and chiral dopants

The helical pitch as a function of the molar ratio of chiral dopants was di scussed based on the host-host, host-dopant and dopant-dopant flexoelectric interactions in a ferroelectric liquid crystal mixture system. It was foun d that the wave number of the pitch approximately changes from quadratic to cubic dependence on the chiral dopant ratio and that the host-dopant flexo electric interactions are negligible compared with the host-host and dopant -dopant interactions.
