Abstract
A water-soluble porphyrinato ytterbium complex linked with rhodamine B (Yb-2) showed mitochondria-specific subcellular localization and strong two-photon-induced NIR emissions (λ em = 650 nm, porphyrinate ligand π → π* transition; λ em = 1060 nm, Yb(III) 5F 5/2 → 5F 7/2 transitions; σ 2 = 375 GM in DMSO) with an impressive Yb(III) NIR emission quantum yield (1% at λ ex = 340 nm; 2.5% at λ ex = 430 nm) in aqueous solution.
