Conjugated organic molecules are interesting materials because of their structures and electronic, electrical, magnetic, optical, biological, chemical properties. However, researchers continue to face great challenges in the construction well-defined compounds that aggregate into larger molecular such as nanowires, tubes, rods, particles, walls, films, other structural arrays. Such nanoscale could serve direct device components. In this Account, we describe our recent progress nanostructures formed through aggregation conjugated investigation electronic properties depend on size or morphology these nanostructures. We have designed synthesized functional with features favor assembly via weak intermolecular interactions. These large-area ordered based a variety simpler fullerenes, perylenes, anthracenes, porphyrins, polydiacetylenes, derivatives. developed new methods construct including vapor−solid phase reaction, natural growth, association self-polymerization self-organization, combination self-assembly electrochemical growth. both facile reliable, allowing us produce aligned nanostructures, arrays nanorods, nanotubes. addition, can synthesize controlled Large-area exhibit optoelectronic also preparation charge transfer (CT) complexes using an solid-phase reaction technique. By process, finely control morphologies sizes wires, rods. Through field emission studies, demonstrate films made from CT kind cathode materials, systematically investigate effects electrical Low-dimension organic/inorganic hybrid be used classes solid not observed either individual nanosize components bulk materials. combined templating technique various nanostructured inorganic semiconductors. The displays distinct optical compared show promise for applications electronics, optics, photovoltaic cells, biology. aim provide intuition understanding structure−function relationships principles lead design concepts development nonhazardous, high-performance
