comparison of the liquidcrystalline properties of these newly prepared compounds containing a bicyclo[3.1.0]hexane core with those of the known analogous compounds with a cyclohexane fragment shows that as a rule, a bicyclo[3.1.0]hexane moiety decreases the transition temperature, while the dielectric (Δϵ) and optical (Δn) anisotropies are comparable. However, the bicyclo[3.1.0]hexane unit has a poorer
