Description

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.
