Abstract:Three substituted cholesteryl benzoate compounds, diazo compound p-H21C10O-C6H4-N-N-C6H4-COOCh, the imine compound p-H21C10O-C6H4-CH-N-C6H4-COOCh, the ester compound p-H21C10O-C6H4-COO-C6H4-COOCh, (Ch as the abbreviation of cholesteryl) were synthesized and their structures were characterized through IR and 1H NMR. The liquid crystal properties were investigated through DSC and polarizing microscope. They show cholesteric phase in the temperature range of 268~312, 231~278 and 203~329℃ for diazo, imine and ester respectively. The effect of central-bridge-bond on the mesophase behavior was discussed.
Keywords:Liquid crystal  Cholesteric phase  Syn thesis
