[摘要]：1,3-dithiole-2-ones attached two cholesteryl through two omega-thioalkanoyloxy spacer of varying length were easily transformed to the appropriate TTF-based unsymmetrical bipedal by cross-coupling reaction in net triethyl phosphite. All of tetrathiafulvalene-based bipedals exhibit mesogenic phases in a wide temperature region, no crystallization but vitrifying to form glassy mesogens during cooling from the isotropic melt. |
