Abstract:Light out of darkness? Most sensitizers for triplet-triplet annihilation (TTA) upconversion are strongly phosphorescent. A new RuII-coumarin dyad, on the other hand, has a non-emissive 3IL excited state (φP=0.2%) but shows a good upconversion quantum yield (φUC=2.7%, see picture, TTET=triplet-triplet energy transfer). © 2011 Wiley-VCH Verlag GmbH & Co.
