Bezzubov, S. I. published the artcileSynthesis, photophysical and electrochemical properties of iridium(III) complexes with 2-aryl-1-phenylbenzimidazoles, Category: imidazoles-derivatives, the publication is Russian Journal of Inorganic Chemistry (2014), 59(6), 571-577, database is CAplus.
A series of mixed-ligand cyclometalated iridium(III) complexes with 2-aryl-1-phenylbenzimidazoles (where aryl is Ph, 4-chlorophenyl, 4-(N,N-dimethylamino)phenyl, 3,4-dimethoxyphenyl, 2-thienyl, and 11-carboxydipyrido[3,2-a:2′,3′-c]phenazine) have been synthesized and characterized by 1H NMR and 31P NMR spectroscopy and mass spectrometry. The electron absorption spectra (EASs) of the complexes are observed to contain charge-transfer bands in the low-energy region (below 600 nm, ε â?(1-3) à 103 mol/(L cm)). The bands experience appreciable bathochromic shifts as the electron-donating properties of a benzimidazole ligand strengthen. The complexes manifest luminescence in the yellow-red spectral region. According to a.c. voltammetry data, reversible and quasi-reversible redox transitions (Eox â?1.2-1.7 V with respect to SHE, CH3CN) are observed in solutions of the studied complexes.
