H2O2-activated triplet–triplet annihilation upconversion via modulation of the fluorescence quantum yields of the triplet acceptor and the triplet–triplet-energy-transfer efficiency

Abstract

Oxidation-activatable triplet–triplet annihilation (TTA) upconversion was achieved with 9,10-bis(diphenylphosphino)-anthracene (BDPPA, nonfluorescent) as an activatable triplet acceptor/emitter, which can be oxidized to BDPPA-O (highly fluorescent) by H2O2 under mild conditions, and thus TTA upconversion was switched on by H2O2.
