Two neutral copper(I) complexes ( 1 and 2 ) bearing deprotonated 2‐(4‐nitro phenyl) imidazole[4,5‐f]‐1,10‐phenanthroline ( NPIP ) and different phosphine ligands (bis[2‐(diphenylphosphino) phenyl]ether ( DPEphos ) and PPh 3 ) were synthesized and characterized. The molecular structure of a representative complex ( 1 ) was established by single‐crystal X‐ray diffraction. The complex features the metal in a distorted tetrahedral environment surrounded by two N atoms of the chelating NPIP ligand and two P atoms from DPEphos ligand. The emission spectra show that the two complexes exhibit yellow emission both in anhydrous ether and in the solid powder form. Density functional theory ( DFT ) calculation was carried out at the B3LYP /6‐ 31G ** level to determine the electronic transition within the molecule.
