Charge regulation in redox active monolayers embedded in proton exchanger surfaces
Experimental evidence of the variation in redox potential of osmium pyridine complexes tethered to a Au surface by thiol or diazonium chemistry at different ionic concentration and electrolyte pH is described. The interplay between the charged redox and acid groups is described by a charge regulatio...

Sumario: | Experimental evidence of the variation in redox potential of osmium pyridine complexes tethered to a Au surface by thiol or diazonium chemistry at different ionic concentration and electrolyte pH is described. The interplay between the charged redox and acid groups is described by a charge regulation model based on PM-IRRAS spectroscopic evidence on the different degrees of surface protonation. © the Owner Societies 2012. |
