Liquid crystal phase diagrams: A study of seven thermotropic materials

Abstract

We report and discuss the pressure–temperature phase diagrams for seven materials having liquid crystal phases: N- (p-methoxybenzylidene) -p-butylaniline (MBBA), N- (p-ethoxybenzylidene) -p-butylaniline (EBBA), N- (p-methylbenzylidene) -p-butylaniline (MBA), cholesteryl oleyl carbonate (COC), 4,4′-bis (heptyloxy) -azoxybenzene (HAB), cholesteryl nonanoate (CN), and N- (p-cyanobenzylidene) -p-octyloxyaniline (CBOOA).
