Abstract

Abstract 2,5-Bis[4′-(dimethylamino)pyridinio]-3,6-difluoro-7,7,8,8-tetracyanoquinodimethane bis(trifluoromethanesulfonate) was obtained as a 1:1 charge-transfer complex with 4-(dimethylamino)pyridine in the reaction of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (TCNQF4) with N-trimethylsilyl-4-(dimethylamino)pyridinium trifluoromethanesulfonate. Its first reduction potential was measured in cyclic voltammetry to be as high as 0.96 V (vs. Ag/AgCl), exceeding that of 2,5,7,7,8,8-hexacyanoquinodimethane (TCNQ(CN)2) by 0.29 V.
