3‐Hydroxypyridin‐2‐one Complexes of Near‐Infrared (NIR) Emitting Lanthanides: Sensitization of Holmium(III) and Praseodymium(III) in Aqueous Solution

Abstract

Ho ho ho! Characteristic visible and near-infrared (NIR) emission bands of the PrIII and HoIII complexes of the tetradentate 1-methyl-3-hydroxypyridin-2-one chromophore are observed in aqueous solution. The HoIII complex has been structurally characterized and, for the first time for a HoIII complex, the kinetics of the luminescence decay in the NIR region have been determined in solution.
