Abstract

© 2017 The Royal Society of Chemistry. The synthesis, characterization, photophysical properties, theoretical calculations, and catalytic applications of 2,9-di(aryl)-1,10-phenanthroline copper(i) complexes are described. Specifically, this study made use of di(aryl)-1,10-phenanthroline ligands including 2,9-di(4-methoxyphenyl)-1,10-phenanthroline (1) , 2,9-di(4-hydroxyphenyl)-1,10-phenanthroline (2), 2,9-di(4-methoxy-3-methylphenyl)-1,10-phenanthroline (3), and 2,9-di(4-hydroxy-3-methylphenyl)-1,10-phenanthroline (4). The 2:1 ligand-to-metal complexes, as PF 6 - salts, i.e., ([Cu·(1) 2 ]PF 6 , [Cu·(2) 2 ]PF 6 , [Cu·(3) 2 ]PF 6 , and [Cu·(4) 2 ]PF 6 ) have been isolated and characterized. The structures of ligands 1 and 2 and complexes [Cu·(1) 2 ]PF 6 and [Cu·(3) 2 ]PF 6 have been determined by single-crystal X-ray analysis. The photoredox catalytic activity of these copper(i) complexes was investigated in an atom-transfer radical-addition (ATRA) reaction and the results showed fai
