Abstract
Six new compounds with chiral terminal chains and three rings bridged via the –COS– and –COO– groups have been synthesized. Three of them belong to series A and have two benzene rings and one bicyclo[2,2,2]octane, while the remaining three come from series B, where all three are benzene rings. Series A compounds share a characteristic feature of two smectic phases: SmA* and SmB*, whereas mesogens from the B series exhibit only the one SmA* phase.
