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

摘要

Asquare-planar Pt(II) complexwith 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.
