四硫富瓦烯（TTF）衍生物在液晶中自组装形成了新型电活性超分子纤维。这些衍生物通过将TTF部分引入衍生自氨基酸如L-异亮氨酸的支架来设计和制备，所述氨基酸的衍生物用作有机胶凝剂。这些基于TTF的胶凝剂在液晶中形成稳定的纤维聚集体。这些纤维是具有电活性部分的氢键键合的一维聚集体的第一个例子，其电导率在掺杂后测量。它们的电子状态也已通过光谱方法表征。在摩擦的聚酰亚胺表面上的取向液晶溶剂中形成单向排列的纤维，用于纤维的进一步官能化。
New electroactive supramolecular fibers have been formed by self-assembly of the derivatives of tetrathiafulvalene (TTF) in liquid crystals. These derivatives are designed and prepared by introducing the TTF moiety to the scaffold derived from amino acids such as L-isoleucine whose derivatives function as organogelators. These TTF-based gelators form stable fibrous aggregates in liquid crystals. These fibers are the first example of hydrogen-bonded one-dimensional aggregates having electroactive moieties whose electrical conductivities were measured after doping. Their electronic states have also been characterized by spectroscopic methods. Unidirectionally aligned fibers are formed in the oriented liquid crystal solvents on the rubbed polyimide surface for further functionalization of the fibers.
