Near-IR phosphorescent metalloporphyrin as a photochemical upconversion sensitizer

Author affiliations

Abstract

The phosphorescent metalloporphyrin sensitizer PtTPTNP (TPTNP = tetraphenyltetranaphtho[2,3]porphyrin) has been successfully coupled with perylenediimide (PDI) or rubrene utilized as triplet acceptors/annihilators to upconvert 690 nm incident photons into yellow fluorescence through sensitized triplet–triplet annihilation at overall efficiencies in the 6–7% range while exhibiting exceptional photostability.
