Effects of trans-cyclohexane sequence in the multiring system molecule on the liquid crystal properties

Abstract

The effects of sequential change of trans-cyclohexane in three-ring and four-ring molecules on their thermal behavior and the phase transition, threshold voltage (Vth), birefringence (Δn) of their mixtures were investigated. The structure with alternate phenyl and cyclohexane go against the stability of the mesomorphic phase, but favor to the decrease of Vth and Δn.
