ABSTRACT:
Optically active naphthalene compounds having the formula: ##STR1## in which X and Y are selected from combinations (a), (b) and (c): (a) X is C.sub.1-10 alkyl or alkoxy and Y is C.sub.4-16 optically active alkyl, (b) X is C.sub.1-10 alkyl or alkoxy and Y is ##STR2## where R.sup.2 is C.sub.4-16 optically active alkyl, (c) X is ##STR3## where R.sup.1 is C.sub.1-10 alkyl or alkoxy and Y is C.sub.4-16 optically active alkyl. Ferroelectric smectic liquid crystal materials being compositions containing these compounds are also described.
