Novel self-assembled monolayers of dipolar ruthenium(III/II) pentaammine(4,4'-bipyridinium) complexes on ultrathin platinum films as redox molecular switches.
We report the first example of a reversible redox-molecular switch based on dipolar ruthenium(III/II) pentaammine(4,4'-bipyridinium) complexes self-assembled on an optically transparent metal electrode, whose change in molecular properties can be simply detected by transmission spectroscopy with a conventional spectrophotometer.
