title: Liquid-Crystalline Properties of trans-A2 B2 -Porphyrins with Extended π-Electron Systems.
abstract: Incorporation of four trialkoxyphenyl substituents combined with extending the π-conjugated system has allowed porphyrins to display liquid-crystalline columnar phases at room temperature. 2D and 3D columnar structures were observed as well as a biaxial smectic phase.
