Liquid crystalline mesophases based on symmetric tetrathiafulvalene derivatives

Abstract

A series of new symmetric tetrathiafulvalene derivatives were designed and synthesized. These compounds have highly ordered lamello-columnar liquid crystalline phases in addition to their crystalline phases at lower temperatures. Charge transport in the organic thin-film-transistor devices is faster in the liquid crystalline phase by two orders of magnitude than that in the crystalline phase due to the decreased defects.
