A Photoluminescent Copper(I) Complex with an Exceptionally High Cu II /Cu I Redox Potential: [Cu(bfp) 2 ] + (bfp=2,9-bis(trifluoromethyl)-1,10-phenanthroline)

A Photoluminescent Copper(I) Complex with an Exceptionally High Cu II /Cu I Redox Potential: [Cu(bfp) 2 ] + (bfp=2,9-bis(trifluoromethyl)-1,10-phenanthroline)

Unprecedented stabilization of the copper(I) oxidation state is demonstrated for the complex cation [Cu(bfp) ] (1) due to the steric and electronic effects of the CF groups (E (Cu /Cu )=+1.55 V vs. SCE). The redox existence range of the copper(I) species is remarkably high at 2.77 V. It is emissive...

Zusammenfassung:Unprecedented stabilization of the copper(I) oxidation state is demonstrated for the complex cation [Cu(bfp) ] (1) due to the steric and electronic effects of the CF groups (E (Cu /Cu )=+1.55 V vs. SCE). The redox existence range of the copper(I) species is remarkably high at 2.77 V. It is emissive in solution at room temperature and shows great potential as a photocatalyst; in the excited state it is a very potent photooxidant.
