Triplet Triplet Annihilation

Near-IR (NIR) absorption from a Cd(ii) texaphyrin (TXP) has been successfully coupled with rubrene triplet acceptors/annihilators in vacuum degassed dichloromethane to upconvert NIR (670–800 nm) incident photons into yellow fluorescence through sensitized triplet–triplet annihilation.
