The three Cu(I) complexes [Cu(POP)(NN′)]PF6, NN′ = 2-(1H-imidazol-2-yl)-5-(naphthalen-2-ylethynyl)pyridine (P1), 2-(1H-imidazol-2-yl)-5-(phenanthren-9-ylethynyl)pyridine (P2), 2-(5-(naphthalen-2-ylethynyl)pyridin-2-yl)-1H-phenanthro[9,10-d]imidazole (P3), were prepared and characterized. The photophys. properties of these Cu(I) complexes is tuned by extending π- system of the NN′ ligand through the addition of polyaromatic groups such as naphthalene and phenanthrene into the pyridine ring part of the diimine ligands via an acetylide linker or phenanthrene-fused imidazole ring. The resulting complexes exhibit higher absorption ability in the visible region. The emissions are in the range of 582-601 nm with quantum yields of 2.30-7.70% and the excited lifetimes of 77.4-115.8 μs for all complexes at room temperature The photophys. properties were further explained by DFT and TDDFT methods.
