Observation of Quantitative Intermolecular Two-Electron Transfer Process through Highly Efficient Singlet Fission in Tetracene Dimer

摘要

Singlet fission (SF) generates two triplet excitons from one photon absorption. This photophysical process theoretically enables to perform the sequential photo-energy conversion process from SF to electron transfer (ET), yielding the radical ion pairs at ~200% quantum yield. However, the high-yield intermolecular ET through SF is generally difficult to achieve for a few reasons.
