Potentiostatic modulation of the lifetime of light-induced charge separation in a heterosupermolecule

A heterosupermolecule has been assembled by covalently linking a TiO2 nanoc rystal, a ruthenium complex, and a viologen. The associated heterosupramole cular function, long-lived light-induced charge separation, has been demons trated. Potentiostatic modulation of this function has also been demonstrat ed. The reported findings and associated insights may find practical applic ations in the area of opticalinformation storage.
