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