A copper(I) phosphine complex with 5,7-dinitro-2-methylquinolin-8-ol as co-ligand

5,7-Dinitro-2-methylquinolin-8-ol has been synthesized, and its copper(I) complex has been prepared. Both the free 2-MequinNO 2 ligand and its complex were characterized by IR, NMR, and UV–Vis spectra. The structure of the [Cu(2-MequinNO 2 )(PPh 3 ) 2 ] complex has been determined by single-crystal...

Summary:5,7-Dinitro-2-methylquinolin-8-ol has been synthesized, and its copper(I) complex has been prepared. Both the free 2-MequinNO 2 ligand and its complex were characterized by IR, NMR, and UV–Vis spectra. The structure of the [Cu(2-MequinNO 2 )(PPh 3 ) 2 ] complex has been determined by single-crystal X-ray analysis. The free 2-MequinNO 2 ligand reveals luminescence in contrast to the complex. For 2-MequinNO 2 , the quantum yield, lifetime of the excited state, and the rate constants of both radiative and non-radiative decay have been determined. The lack of luminescence for the complex has been explained with the use of a quantum chemical study.
