2-lodo-(1) and 2,6(7)-diiodo-tetrathiafulvalenes (2a, 2b) have been synthesized in good yields, by treating the corresponding lithiated intermediates of TTF with perfluorohexyl iodide; the X-ray crystal structures of 1 and 2a have been determined.

Bis- and tetrakis(triphenylstannyl)tetrathiafulvalenes were prepared from the corresponding lithio-derivatives and chlorotriphenyltin, and their structures were determined by X-ray analysis. Their absorption maxima in the electronic spectrum showed a bathochromic shift. Their redox potentials shifted only a little to a lower region. The charge-transfer complex of the tetra-substituted derivative with
由相应的硫代衍生物和氯代三苯基锡制备了双(三苯基锡烷基)和四(三苯基锡烷基)四硫富瓦烯,并通过X射线分析确定了它们的结构。它们在电子光谱中的吸收最大值显示出红移。它们的氧化还原电势仅转移到较低的区域。分离了四取代衍生物与TCNQ的电荷转移络合物。双(三甲基锡烷基)四硫富瓦烯不与(η- Cp)(CO)2 FeI反应,与(COD)PtCl 2反应,然后添加三丁基膦,得到复杂的混合物,由该混合物可以得到(C 2 H 2 S 2)铂(PBu 3)2分离产率低。通过X射线衍射确认了结构。还报道了方便的四硫富瓦烯和四碘四硫富瓦烯的制备方法。
A new molecular wire suitably functionalized with sulfur atoms at terminal positions and endowed with a central redox active TTF unit has been synthesized and inserted within two atomic-sized Au electrodes; electrical transport measurements have been performed in STM and MCBJ set-ups in a liquid environment and reveal conductance values around 10–2G0 for a single molecule.
