| Abstract: | A new series of trifluoromethyl liquid crystals, the 4-n-alkoxybenzylidene-4′-trifluoromethylanilines, has been synthesized. All members of the series with three carbons or more in the alkoxy chain are enantiotropic smectics. There is an odd:even effect in the smectic-isotropic transition temperatures. The smectic phase is of the B type. Members of this series strongly promote enhanced smectic A phases in many binary mesophase systems. |
