Tilt angle behavior of smectic C phase

Abstract The tilt angle behavior of the smectic C phase of single compounds and binary mixtures which were doped with 1wt% of a chiral dopant was investigated by using surface-stabilized ferroelectric liquid crystal cells. The effect of the molecular structure of single compounds on the tilt angle was investigated. The effect of the mixing of two compounds with different molecular structures on the tilt angle was investigated. It was found that the tilt angles correlated to the ratio of the SC -SA transition temperature to the SA -N (or I) transition temperature.
