Spiroconjugated TTF-type electron donors (13a−c) and TCNQ-type electron acceptors (10, 11) have been prepared from spiroquinone 9. Cyclic voltammetry reveals a relatively weak accepting ability for 10 and 11, and a strong electron-donor character for 13a−c. Whereas the spiroconjugation introduces a destabilization of the LUMO for compounds 9−11, the opposite is observed for compound 13, thus justifying the redox potential values.
