摘要：

The paramagnetic complex (L2-.) Ru(II) (bpy)2, where L2-.= 5-methyl-2-oxido-1,4-benzosemiquinone and bpy = 2,2'-bipyridine, was studied because the quinonoid form LH is a model of the topaquinone (TPQ) cofactor of certain copper-dependent amine oxidases. For the metal complex the potential ortho- and para-quinonoid character of the LH(n) system was probed by high resolution EPR spectroscopy of the semiquinone state which could be obtained through oxidation of the basic catecholate form.
