Trithienylenevinylenes having amide end functional groups form supramolecular gels in nonpolar solvents, comprised of self-assembled nanowires. These gels exhibit the unique property of solution phase epitaxy leading to the alignment of fibers on mica surface. FP-TRMC studies revealed high charge carrier mobility for xerogels from decane-chloroform whereas films obtained from chloroform solutions showed less mobility, highlighting the role of self-assembly and gelation on the electronic properties of semiconducting molecular gelators. This study opens the window for a new class of conducting gelators which may find wide application in organic electronic devices.
具有酰胺端基官能团的三噻吩乙烯基在非极性溶剂中形成超分子凝胶，由自组装纳米线组成。这些凝胶表现出独特的溶液相外延性质，导致纤维在云母表面上的排列。FP-TRMC 研究表明，来自癸烷-氯仿的干凝胶具有高电荷载流子迁移率，而来自氯仿溶液的薄膜则表现出较低的迁移率，这突出了自组装和凝胶化对半导体分子凝胶剂电子性质的作用。这项研究为一类新型的导电凝胶剂开辟了道路，它们可能在有机电子器件中有广泛的应用。
