Supramolecular self-assembly of a novel acceptor-π-porphyrin-π-acceptor compound driven by intermolecular sulfur-sulfur interactions leads to the formation of J-aggregates composed of helical nanowire structures. These nanowires have exhibited interesting optical activity, and when utilized as a molecular electron donor with a fullerene acceptor in bulk heterojunction organic solar cells, a high photovoltaic power conversion efficiency of over 8% has been achieved.
