Abstract

Binding of chloride anion to a tetrathiafulvalene calix[4]pyrrole (TTF-C4P) donor results in ET to Li ⁺@C ₆₀ to produce the radical pair (TTF-C4P ^•+/Li ⁺@C ₆₀ ^•-), the structure of which was characterized by X-ray crystallographic analysis. The addition of tetraethylammonium cation, which binds more effectively than Li ⁺@C ₆₀ ^•- as a guest within the TTF-C4P cavity, leads to electron back-transfer, restoring the initial oxidation states of the donor and acceptor pair.
