Electrostatic Assembled Films EAF

V = lOOmV s (inset /peak [NADH]). Electrolyte 0.25 M LiCF3S03, acetate buffer 0.05 M, pH = 4.7. The structure of M-TRP is shown at the center. S 

O2 saturated solution. Electrolyte 0.10M LiCF3S03 aqueous solution. 

Recently, a MnTPyP species with four [Ru (bpy)2(OH2)] complexes coordinated to the pyridyl-substituents were synthesized and characterized. The oxidation of the peripheral aqua-complexes led to formation of [O = Ru (bpy)2], a known oxygen-atom transfer catalyst. The films of this peripherally metal-lated porphyrin are too soluble, but can be stabilized by anion-exchange with [Fe(CN)6] or M-TPPS. The oxidation of nitrite occurred at 1.0 V and was catalyzed by that high-valent species.
