综述了环状四硫富瓦烯（TTF）的合成及其氧化还原电位等物理性质。环闭合通常以两种不同方式中的一种进行：（i）通过偶联1，3-二硫醇衍生物从而形成中心富烯键，或（ii）通过环化预先形成的TTF衍生物。当使用氰乙基保护/脱保护方法时，第二种途径是非常有效的，并且使得制备许多二维和三维大环化合物，例如单-、双-和四大环化合物、低聚大环化合物和笼型分子成为可能。在超分子化学中使用的四硫富瓦烯吩也举例说明在这个微观审查。
The syntheses and some physical properties (redox potentials) of cyclic tetrathiafulvalenes (TTF) are reviewed. The ring closure is generally performed in one of two different ways: (i) by coupling of 1,3-dithiol derivatives thereby forming the central fulvene bond, or (ii) by cyclization of a preformed TTF derivative. The second route is very efficient when using the cyanoethyl protection/deprotection method and has made possible the preparation of a number of two- and three-dimensional macrocycles, e.g. mono-, bis- and tetramacrocycles, oligomeric macrocycles and cage-type molecules. The use of tetrathiafulvalenophanes in supramolecular chemistry is also exemplified in this microreview.
