Abstract

A new class of mesogenic compounds, the perhydroazulenes, carrying substituents in their para positions (HAZ derivatives), has been synthesized. The new liquid crystalline materials display a broad enantiotropic nemantic mesophase slightly above room temperature without any additional smectic phase. Their physical properties reveal that the perhydroazulene moiety can replace the currently often used cyclohexyl and biscyclohexyl units in liquid crystalline materials.
