title: Optically Active Cubic Liquid Crystalline Phase Made of Achiral Polycatenar Stilbene Derivatives.
abstract: Achiral stilbene polycatenars forming smectic, columnar or cubic phase depending on the terminal chains length, were studied. The cubic Im3m phase exhibited optical activity originating in twisted face-to-face molecular aggregates. The optical activity of the phase is preserved upon sample crystallization, providing evidence of a transfer of chirality on a molecular level.
