Electron Transferto Colloidal ZnO Nanocrystals fromthe Excited State of a Perylene Chromophore Formed by Direct Excitationor Triplet–Triplet Annihilation Upconversion

Abstract Upon binding 4-(perylen-3-yl)benzoic acid 1, to oleate-capped ZnO nanocrystals (NCs), significant broadening of the perylene absorption spectrum and fluorescence quenching were observed. In contrast, no broadening of the absorption spectrum or fluorescence quenching was...
