Implication
Experimental study reveals strong stabilization of photolytically generated radical pairs in novel C60-based dyads, highlighting the structural roles of aromaticity and planarity.
Key Points
- Investigate the molecular mechanisms that stabilize photolytically generated radical pairs in novel fullerene (C60)-based donor-acceptor dyads.
- Synthesized molecular dyads coupling fullerene (C60) electron acceptors with π-extended tetrathiafulvalene (TTF) electron donors.
- Examined photolytic electron-transfer dynamics and radical-pair stability associated with donor oxidation.
- Oxidation of the π-extended tetrathiafulvalene donor induces a simultaneous gain in molecular planarity and aromaticity.
- Conformational planarization and enhanced aromaticity provide substantial stabilization to photolytically generated radical pairs within the dyads.
