Water-Induced Changes of Photoluminescence of a Pincer-Type N-Heterocyclic Carbene Platinum(II) Complex

Abstract

A square-planar Pt(II) complex with a pyridine-based pincer-type N-heterocyclic carbene ligand, [PtII(C∧N∧C)(Cl)]Cl (C∧N∧C = 2,6-bis(1-butylimidazol-2-ylidenyl)pyridine), was synthesized as a new type of emitter and structurally characterized. The complex shows aquachromic photoluminescence in the solid state upon hydration and dehydration.
