摘要
Radical bridge design: The diquinone-tetrathiafulvalene (TTF) species shown exhibits effective electron coupling between the quinone centers which is mediated by the TTF bridge. Stepwise one-electron reduction of the molecule occurs, and the observed potential difference between reduction events is an indication that reduction of the second quinone unit is affected by the radical species already formed on the other side of the bridge.
