Photoluminescence of (quinap)tricarbonylrhenium(I) chloride with quinap=1-(2-diphenylphosphino-1-naphthyl)isoquinoline

The complex (quinap)ReI(CO)3Cl, with quinap =1-(2-diphenylphosphino-1-naphthyl)isoquinoline, shows a luminescence at λmax=582 nm with φ=0.12 and τ=1.4 μs in solution (e.g., CH2Cl2) at r.t. It is suggested that this emission originates from a ReI to quinap metal-to-ligand charge transfer triplet.
