A unique approach for self-assembly of organic semiconductors is presented, utilizing the functional dipyrrollopyridine heterocycle as a complimentary H-bonding partner for naphthalene and perylene diimides. Molecular and polymeric assemblies are examined, with studies focusing on the optical, morphological, and semiconducting properties of the resulting structures. Assembly in solution leads to interesting charge transfer behavior mediated through the three point H-bonding motif, which could offer a new route to efficient photoexciton formation in wide band-gap materials. In addition, the potential uses of this supramolecular approach for morphology engineering is discussed with a focus on optoelectronic devices including light emitting transistors and photovoltaics.
