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.
