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.
