Abstract
A series of compounds having an aminopropenone-3 group between two aromatic rings has been synthesized and thermally stable enantiotropic mesogens with properties typical of three ring liquid crystals were obtained. The mesomorphic properties of the molecules result from the presence of a rigid calamitic core stabilized by a hydrogen-bonded cis-s-cis quasi-ring form of the enaminoketone group.Keywords
