Thiophene-fused tetracyanoquinodimethanes as electron acceptors for conducting charge-transfer salts
Abstract
Four isomeric benzodithiophene analogues of 11,11,12,12-tetracyano-9,10-anthraquinodimethane (1)–(4) have been prepared, in which (1) and (2) exhibited excellent reduction potentials as electron acceptors and formed highly conducting charge-transfer complexes with tetrathiafulvalene.
