[60]Fullerene–perchlorotriphenylmethide anion triads. Synthesis and study of photoinduced intramolecular electron-transfer processes†
Abstract
For the first time an anionic donor, the perchlorotriphenylmethide anion (PTM−), has been covalently bonded to C60, generating the C60–(PTM−)2 triad that is reversibly oxidized to the corresponding C60–perchlorotriphenylmethyl radical triad C60–(PTM˙)2. For the triad C60–(PTM−)2, photoinduced charge-separation can be confirmed to occur via the excited singlet states of the C60 moiety and the PTM anion in polar and nonpolar
