Abstract

The local distribution of exciton levels in disordered cyanine-dye-based molecular nanoaggregates has been elucidated using fluorescence line narrowing spectroscopy. The observation of a Wigner-Dyson-type level spacing distribution provides direct evidence of the existence of level repulsion of strongly overlapping states in the molecular wires, which is important for the understanding of the level statistics, and therefore the functional properties, of a large variety of nanoconfined systems.
