| titleOfInvention |
N-substituted amino acid derivatives for use in liquid crystal materials and devices |
| abstract |
Novel compounds suitable for use as chiral dopants in ferroelectric smectic liquid crystal materials comprising an optically active derivative of an α-amino acid of the formula ##STR1## wherein R 1 is selected from the group consisting of C 1-20 alkyl or alkoxy, R is C 1-20 n-alkyl and Y is C 1-20 alkyl. A liquid crystal mixture and a device using these compounds are also described. |
