The synthesis and properties of some chiral mesomorphic quaterphenyl and cyclohexylterphenyl derivatives and the FLC compositions based upon them

Abstract

This paper describes the synthesis and mesomorphic properties of some new liquid crystalline quaterphenyl and cyclohexylterphenyl derivatives – the Ferroelectric liquid crystal (FLC) compositions based upon them. The FLC compositions containing the new quaterphenyl derivatives are characterised by a wide temperature range of the Sm-C* phase, a low operating voltage and a very good quality of orientation in the cells (thermal and the mechanical stable ‘shock-free’).
