Miscibility studies of 2-3-difluoro-4-pentylterphenyl-4-yl carbonate with ferroelectric compounds

Abstract

Three chiral compounds, containing three aromatic rings in a rigid core, forming ferroelectric phase were doped with non chiral difluorosubstituted terphenyl carbonate compound. The influence of the structure and the amount of terphenyl carbonate compound on the stability and helical pitch of the ferroelectric phase in binary mixtures was examined. It was found that thermal stability of the SmC* phase of chiral compounds has increased. Addition of terphenyl carbonate compound slightly increases the helical pitch (except for one of the binary mixture).[b]Keywords[/b]: chemistry, liquid crystals, ferroelectric phase, miscibility studies, optical microscopy, helical pitch
