Ruthenium (II) tribipyridine functionalized gold nanorods. Morphological changes and excited-state interactions

The functionalization of gold nanorods with a thiol derivative of ruthenium (II) tribipyridyl complex in dodecanethiol is described. The results suggest that the size and shape of the gold nanorods impact the quenching of the excited state to proceed via an energy transfer mechanism and those gold rods are capable to deactivate excited ruthenium.
