2,6-bis(dicyanomethylene)-2,6-dihydrobenzo[1,2-b:4,5-b′]dithiophene as a novel electron acceptor

Abstract The title-TCNQ involving the the 2,6-quinoid skeleton of benzo[1,2- b :4,5 b ′]dithiophene has been prepared in order to design a superior electron acceptor with both a strong electron-accepting ability and a strong heteroatomic interaction. The cyclic voltammetry demonstrated that it corresponds to a potential electron acceptor comparable to TCNQ. It thus formed highly conductive complexes with the following electron donors: TTT, 4,5 Scm −1 ; HMTTeF, 25 Scm −1 ; DMTTeA, 0.07 Scm −1 ; TPBP, 0.54 Scm −1 .
