Optical properties of Ag(tripod)X with tripod = 1,1,1-tris(diphenyl-phosphinomethyl)ethane and X − = Cl − and I −: Intraligand and ligand-to-ligand charge transfer

Abstract

The complexes Ag I(tripod)X with tripod = 1,1,1-tris(diphenylphosphinomethyl)ethane and X − = Cl − and I − are luminescent in solution at r.t. It is suggested that the emission is a phosphorescence which originates from a tripod intraligand state for X = Cl ( λ max = 464 nm) and a X − → tripod ligand-to-ligand charge transfer state for X = I ( λ max = 482 nm).
