Synthesis and Characterization of 2-(2,4-Dibromophenol)-1H-imidazole [4,5-f][1,10] Phenanthroline and Its Copper(I) Compounds

Abstract

2-(2,4-Dibromophenol)-1H-imidazole[4,5-f][1,10]phenanthroline (DIPP) was obtained by reaction of 3,5-dibromo-salicylaldehyde and 5,6-diamine-1,10-phenanthroline. Five cupprous complexes with diphosphine and DIPP ligands were acquired by reaction of [Cu(CH3CN)4]ClO4, DIPP and chelating diphosphine. Some photophysical properties and structures of the complexes are preliminarily characterized by ultraviolet visible (UV-Vis) electron absorption spectra, fluorescence spectra and infrared spectroscopy (IR) etc. The results show that these complexes exhibit good emission behavior at room temperature.
