General description

Cholesteryl benzoate (CB) is a cholesteryl ester which is used in cholesteric liquid crystals by forming layered spiral staircases in which the rotation angle is temperature dependent.

Application

Cholesteryl benzoate (CB) is a structure directing agent which can be used in the growth of oriented lithium iron phosphate (LiFePO4) for the fabrication of lithium ion batteries. It can be used in the fabrication of polymer dispersed liquid crystals (PDLC) which show liquid crystallinity by cooling the material from the isotropic phase.

Phase behaviour and some physicochemical properties of cholesteryl benzoate-contained microemulsions of xylene and heptane with water using sodium deoxycholate and butan-1-ol as surfactant and co-surfactant respectively have been studied. While the microemulsion area of xylene depends insignificantly on the surfactant/co-surfactant
