A series of phenanthroline-based ligands have been synthesized and their influence as bidentate nitrogen ligands in heteroleptic [Cu(PP̂)(NN̂)]+ photosensitizers in light-driven water reduction has been studied. In this noble-metal-free Cu-Fe-based photocatalytic water reduction system, the structural effects of the nitrogen ligands have been explored, including the steric and electronic effects of substituents at the 2,9- and 4,7-positions of phenanthroline. Ligands were prepared that led to increased hydrogen generation, with turnover numbers (TONCu) of up to 1388 being observed All the new complexes were electrochem. and photophys. characterized. We demonstrate for the first time that the presence of fluorine in nitrogen ligands increases the efficacy of copper complexes in photocatalytic hydrogen production The experimental part of the paper was very detailed, including the reaction process of 4,7-Bis(4-bromophenyl)-1,10-phenanthroline(cas: 97802-08-9SDS of cas: 97802-08-9)
4,7-Bis(4-bromophenyl)-1,10-phenanthroline(cas: 97802-08-9) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.SDS of cas: 97802-08-9
