Herein we report construction of supramolecular charge-transfer complex one-dimensional (1D) nanowires consisting of highly ordered mixed-stack π-electron donor-acceptor (D-A) domains. We synthesized n-type and p-type β-sheet forming short peptide-chromophore conjugates, which assemble separately into well-ordered nanofibers in aqueous media. These complementary p-type and n-type nanofibers coassemble via hydrogen bonding, charge-transfer complex, and electrostatic interactions to generate highly uniform supramolecular n/p-coassembled 1D nanowires. This molecular design ensures highly ordered arrangement of D-A stacks within n/p-coassembled supramolecular nanowires. The supramolecular n/p-coassembled nanowires were found to be formed by A-D-A unit cells having an association constant (KA) of 5.18 × 105 M-1. In addition, electrical measurements revealed that supramolecular n/p-coassembled nanowires are approximately 2400 and 10 times more conductive than individual n-type and p-type nanofibers, respectively. This facile strategy allows fabrication of well-defined supramolecular electroactive nanomaterials in aqueous media, which can find a variety of applications in optoelectronics, photovoltaics, organic chromophore arrays, and bioelectronics.EnglishCoassemblyConductivityNanowiresPeptide chromophoreSelf-assemblySupramolecularCharge transferElectric conductivityFabricationHydrogen bondsNanofibersNanostructured materialsNanowiresPeptidesSelf assemblySupramolecular chemistryCharge transfer complexCoassemblyElectrical measurementElectroactive materialElectron donor acceptorsOne-dimensional (1D) nanowiresOrganic chromophoresSupramolecularChromophoresArticle10.1021/acsnano.7b02025
