Abstract
The present invention provides new optically active 2,5-diphenyl pyrimidine derivatives, optically active liquid crystal compositions containing the derivatives and electro optical elements comprising the compositions. The derivatives have the following general formula: ##STR1## wherein R indicates an alkyl or alkoxy group having 2-20 carbon atoms and R* indicates an optically active alkyl group having 4-20 carbon atoms.
Claims8
A 2,5-diphenyl pyrimidine derivative represented by the formula:
- ##STR13## wherein R is alkyl of 5-15 carbon atoms, and R* is optically active alkyl of 5-11 carbon atoms.
Dependencies are inferred from the claim text.
