Photocytotoxic copper(II) complexes of N-salicylyl-l-tryptophan and phenanthroline bases

The mechanistic diversity of the selective aerobic oxidation of alcohols catalyzed by systems derived from CuI and a diamine ligand

“…The latter band particularly belongs to the characteristic d–d transition of Cu( ii ) species. 55–57 Then bubbling O 2 into the solution further increased the intensities of the two bands, indicative of the complete oxidation of Cu( i ) species. After the addition of 1-octanol, the intensity of the bands in the two regions kept increasing with no significant change in the peak wavelengths, which suggests that the substrate-binding product was still Cu( ii ).…”

A fundamental role of the solvent polarity and remote substitution of the 2-(4-R-phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline framework in controlling the ground- and excited-state properties of Re(i) chromophores [ReCl(CO)3(R-C6H4-imphen)]

“…1–20 Possessing the 1,10-phenanthroline unit with strong abilities to bind transition metals, imidazo[4,5- f ][1,10]phenanthrolines have also become very popular ligands for controlling the photophysical and antiproliferative behaviour of transition metal complexes. They have been combined with numerous transition metal ions including Cu( i ), 21–25 Cu( ii ), 26–28 Ru( ii ), 29–40 and Ir( iii ). 41–46 The vast majority of these coordination compounds have potential uses in anticancer therapy, 26–28,31,34–37,39–46 bioimaging, 32,47 the conversion of solar energy, 22,29 organic light-emitting diodes, 21,23,48–50 photoredox catalysis, 38,51,52 and luminescence sensing.…”
