Two Neutral Copper(I) Complexes Bearing 2‐(4‐Nitrophenyl) Imidazole[4,5‐f]‐1,10‐Phenanthroline: Synthesis, Crystal Structure, and Luminescence Properties

Abstract

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.

“…The rational design of metal-organic complexes has received remarkable attention and has developed rapidly due to their fascinating potential applications in functional materials, [4][5][6][7][8][9][10][11]. All aspects of this research hotspot have been deeply discussed by some recent reviews, which show that the diverse structures of such materials are always dependent on many factors, such as substituent and number of coordination sites provided by organic ligands, ligand to metal salt ratio, template, metal ion, pH value, and counteranion [12].…”
