Summary of "Collective Response in DNA-Stabilized Silver Cluster Assemblies from First-Principles Simulations."

We investigate fluorescence resonant energy transfer and concurrent electron dynamics in a pair of DNA-stabilized silver clusters. For this purpose we introduce a methodology for the simulation of collective opto-electronic properties of coupled molecular aggregates starting from first-principles quantum chemistry, which can be further applied to a broad range of coupled molecular systems to study their electrooptical response. Our simulations reveal the existence of a low-energy coupled excitonic states, which enable ultrafast energy transport between subunits, and give an insight into the origin of the fluorescence signal in coupled DNA-stabilized silver clusters, that have been recently experimentally detected. Hence we demonstrate the possibility to construct an ultrasmall energy transmission lines and optical converters based on these hybrid molecular systems.
