Abstract:

Coordination of IrCl5acetonato minus 2 values in acetone methylene chloride to a film of vinyl-pyridine RF plasma polymerized on a carbon electrode results in an electrode surface wave at 0.40 volt vs. S.C.E. in 1 M H2SO4. This potential is more negative than expected for -PyIrCl5 minus 2 values coordination. Charge transport in the film is very fast and the film catalyzes the oxidation of ascorbic acid at a diffusion controlled rate. The film electrochemistry is sensitive to the choice of supporting electrolyte cation but not anion. Author
