Synthesis And Property Of Some Tetrathiafulvalene Derivatives

In this paper, we first introduced the main research branches about the tetrathiafulvalene. Subsequently Via adjusting the nucleophilicity of aromatic amine, extended-conjugation N-aryl-l,3-dithiolano[4,5-c]pyrrole-2-thione was designed and synthesized first, using readily available 4,5-bis(bromomethyl)-l,3-dithiole-2-thione (66) as starting materials. Then through common coupling method we got a series of N-Aryl- pyrrolo [3,4-c]annelated Tetrathiafulvalene derivatives (70e, 72b, 72c, 72d, 72e, 80g, 83 and 84) for the first time and study their electrochemical property of all these TTFs by Cyclic Voltammetry. All these compounds have comparable or better half-wave oxidation protentials than that of N-alkyl-pyrrolo-annelated TTFs that have been reported previously.We also attempt to synthesize TTF derivatives containing carbonyl group(59 and 62) by coupling before introducing carbonyl group.Synthesis trial of bispyrrolo-annelated BEDT-TTF was made in this paper as well.
