Tetrathiafulvalenyl-thiol (1), disulfide (2), thioacetate (3), and sulfide (4) have been prepared. The redox behaviors of the tetrathiafulvalene derivatives (1-3) depended on the nature of an electrolyte and a solvent used. Though a difference of electrochemical behavior between 1 and 2 was found in the cyclic voltammograms, the self-assembled monolayers (SAMs) from 1 and 2 showed the similar redox behaviors, while, 4 did not form SAM on a gold (Au) electrode.
