New Substituted Tetrathiafulvalene−Quinone Dyads: The Influences of Electron Accepting Abilities of Quinone Units on the Metal Ion-Promoted Electron-Transfer Processes

The metal ion-promoted electron transfer occurs to all new dyads 1, 2, 3, and 4, even one of them, dyad 4, which has a rather weak electron acceptor unit. The results also indicate that the metal ion-promoted electron transfer within the dyads is influenced by the electron accepting abilities of quinone units; dyad 2 with the strongest electron acceptor among the four dyads shows the strongest absorption and ESR signals attributed to TTF·+ in the presence of metal ions.
