Naphthylazoimidazole complexes of tetracarbonylchromium and molybdenum: Synthesis, spectra, electrochemistry and photophysical studies
摘要:
A new series of Cr(O)- and Mo(O)-carbonyl complexes of 1-alkyl-2-(naphthyl-alpha/beta-azo)imidazoles (alpha/beta-NaiR') are described in this work. The complexes are formulated cis-[M(CO)(4)(alpha/beta-NaiR')] by elemental, mass and other spectroscopic data. The complexes are stable and exhibit emission spectra at room temperature. Cyclic voltammetry shows two metal centred oxidations, M+/M-0 and M2+/M+, and two ligand centred reductions, azo/azo(-) and azo(-)/azo(=). (c) 2006 Elsevier Ltd. All rights reserved.
