Platinum(II) Complexes of Tridentate (NN- boolean AND N)-N-boolean AND -Coordinating Ligands Based on Imides, Amides, and Hydrazides: Synthesis and Luminescence Properties
Five Pt(II) complexes are described in which the metal ion is bound to anionic (NNN)-N-boolean AND-N-boolean AND-coordinating ligands. The central, deprotonated N atom is derived from an imide Ar-C(=O)-NH-C(=O)-Ar {PtL1-2Cl; Ar=pyridine or pyrimidine}, an amide py-C(=O)-NH-CH2-py {(PtLCl)-Cl-3}, or a hydrazide py-C(=O)-NH-N=CH-py {(PtLCl)-Cl-4}. The imide complexes PtL1-2Cl show no significant emission in solution but are modestly bright green/yellow phosphors in the solid state. (PtLCl)-Cl-3 is weakly phosphorescent. (PtLCl)-Cl-4 is formed as a mixture of isomers, bound through either the amido or imino nitrogen, the latter converting to the former upon absorption of light. Remarkably, the imino form displays fluorescence in solution, lambda(0,0)=535 nm, whereas the amido shows phosphorescence, lambda(0,0)=624 nm, tau=440 ns. It is highly unusual for two isomeric compounds to display emission from states of different spin multiplicity. The amido-bound (PtLCl)-Cl-4 can act as a bidentate (ON)-N-boolean AND -coordinating ligand, demonstrated by the formation of bimetallic complexes with iridium(III) or ruthenium(II).
