Triply phenanthryl‐ and tetrahelicenyl‐substituted triazine‐hexaalkyl esters with short alkyl chains show glass transitions conveniently above room temperature within the hexagonal columnar liquid crystalline state, resulting in a solid columnar order at room temperature. As the hexagonal columnar mesophase is easily aligned with the director perpendicular to a solid substrate, such glassy columnar...
Whereas their para homologs are not mesogenic, the disk‐shaped triphenyltriazine meta‐trialkylesters obtained via trimerization of 3‐cyanobenzoic alkylester, which are configurationally more flexible, exhibit a monotropic nematic mesophase. Introduction of fluorine atoms into the alkyl chains or into the phenyl moieties leads to the appearance of an enantiotropic columnar mesophase. If fluorine is...
