Liquid crystals esters

A liquid crystal ester has a structure: where X and Y are fluorine or hydrogen at least one being hydrogen, and Z is either: (a) where R2 is alkyl, alkoxy, alkylcarbonyloxy or alkoxycarbonyloxy (b) where R3 is an alkyl group. The ester may be prepared by a conventional esterification from the corres...

Summary:A liquid crystal ester has a structure: where X and Y are fluorine or hydrogen at least one being hydrogen, and Z is either: (a) where R2 is alkyl, alkoxy, alkylcarbonyloxy or alkoxycarbonyloxy (b) where R3 is an alkyl group. The ester may be prepared by a conventional esterification from the corresponding phenol and the corresponding acid chloride Z-COCl. The ester may be used in mixtures with other liquid crystal compounds for use in known electro-optic devices.
