Synthesis, structure, luminescence and electrochemical studies of a novel class of ruthenium(II) polypyridine complexes with ortho-metallated aminocarbene ligands

摘要

A series of ruthenium(II) orthometallated aminocarbene complexes have been synthesized and characterized. Their electronic absorption, emission. and the crystal structures of [Ru(phen)_2{=C(CH_2Ph)NHC_6H_4}]-CF_3SO_3. [Ru(bpy)_2{=C(CH_2Ph)NMeC_6H_4}]PF_6 and [Ru(bpy)_2{=C(CH_2C_4H_3S)NHC_6H_4}]CF_3SO_3 have been studied. The nature of the electronic transitions and the origin of the emission are discussed and an assignment of a ~3MLCT emission has been supported by EHMO studies.
