Zusammenfassung der Projektergebnisse

We presented the first comprehensive investigation regarding the covalent attachment of a light harvester / electron donor, that is, a phthalocyanine, to the basal plane of few layer graphene, on one hand, and its full-fledged physico-chemical characterization, on the other hand. Most importantly, the latter included the unambiguous corroboration by means of several steady-state and time-resolved assays of an ultrafast charge separation followed by a slower charge recombination.
