The synthesis and properties of 1,3-dihydro-1,3-bis(dicyanomethylene)isothianaphthene 1 and its higher homologue 1,3-bis(1,3-dicyanovinylene)isothianaphthene 2 are reported; these compounds, which are the first electron acceptors of the isothianaphthene series, show electrochemical behaviour that contrasts with that of their thiophene analogues; the molecular structure of 1 was determined by X-ray analysis.
