New series of bis-fused tetrathiafulvalene contains functional groups was newly synthesized. The synthesis was carried out by using routes involving cross coupling, reduction, oxidation, and Wittig-type reactions. The identity of these new donors is confirmed by NMR1H, mass spectrometry, and elemental analysis. We have used the cyclic voltammetry in order to determine the character donors-π of these molecules and to verify the reversibility of the redox process involved. Molecular orbital diagram has been calculated using density-functional calculations. Charge transfer complexes with tetraflurotetracyano-quinodimethane (TCNQF4) were prepared by chemical redox reactions.
