Available in PDF, EPUB and Kindle. Book excerpt: Here, we present a completely solid-phase synthetic strategy to create three- and four-fold peptide-appended [pi]-electron molecules, where the multivalent oligopeptide presentation is dictated by the symmetries of reactive handles placed on discotic [pi]-conjugated cores. Carboxylic acid and anhydride groups were viable amidation and imidation partners, respectively, and oligomeric [pi]-electron discotic cores were prepared through Pd-catalyzed cross-couplings. Due to intermolecular hydrogen bonding between the three or four peptide axes, these [pi]-peptide hybrids self-assemble into robust one-dimensional nanostructures with high aspect ratios in aqueous solution. The preparation of these systems via solid-phase methods will be detailed along with their self-assembly properties, as revealed by steady-state spectroscopy and transmission electron microscopy and electrical characterization using field-effect transistor measurements.
