ABSTRACT:
Substituted-hydrocarbylthio phenyl-pyrimidines are disclosed which exhibit smectic A phases over a wide temperature range and are useful in formulating smectic A compositions. The liquid-crystal compositions formulated utilizing the smectic A compounds of the present invention have particular application in smectic cells such as laser smectic liquid-crystal light valves and optical limiters used in high performance environments.
