High-yield singlet fission in a zeaxanthin aggregate observed by picosecond resonance Raman spectroscopy.

Chen Wang1, Michael J Tauber.   

Abstract

We report high-yield triplet generation by singlet fission upon photoexcitation of a new aggregate of the carotenoid all-trans 3R,3'R-zeaxanthin. The yield is determined by picosecond time-resolved resonance Raman spectroscopy, which allows direct characterization and quantification of triplet excited-state signatures and ground-state depletion. The technique and analysis reveals that triplets form within picoseconds. A quantum yield of 90-200% is derived with the assumption of weak exciton-coupling in the zeaxanthin aggregate.
