Abstract of the Disclosure Octa-substituted derivatives of the macrocyclic tetramers obtained by condensation of resorcinol with an alkyl aldehyde, wherein the substituents are alkanoyl, p-alkylbenzoyl, and p-alkoxybenzoyl chains. These substituted tetramers show stable, tridimensional, columnar type mesophases wherein the crystalline lattice is formed with the central macrocyclic rings stacked one on another according to ordered columns, each ring being surrounded with alkyl chains in the melted state.
