The bipedal 1,3-dithiole-2-thiones and the appropriate EDT-TTFs bearing two cholesteryl linked with two ω-thioalkanoyloxy spacers of varying length were synthesized. All of bipedals showed mesogenic phases in a wide temperature region, no crystallization but vitrifying to form glassy mesogens during cooling from the isotropic melt.
