Novel Liquid Crystalline Compounds Containing Bicyclo[3.1.0]hexane Core Units. -Compared to isomorphous liquid crystalline compounds containing a 1,4-disubstituted cyclohexane moiety, the newly prepared bicyclic compounds (I) have comparable dielectric and anisotropic anisotropies, but, as a rule, the bicyclo[3.1.0]hexane moiety decreases the transition temperature. In general, the bicyclo[3.1.0]hexane derivatives have a poorer mesogenic potential than the isomorphous cyclohexane derivatives. -(KOZHUSHKOV, S. I.; LANGER, R.; YUFIT, D. S.; HOWARD, J. A.
