专利号:US-9334304-B2 优先权日:2009-04-02 标 题:Self-assembling peptides bearing organic electronic functionality and applications employing the same 发明人:TOVAR JOHN DAYTON; DIEGELMANN STEPHEN ROBERT; WALL BRIAN D; VADEHRA GEETA SOPHIE 权利人:TOVAR JOHN DAYTON; DIEGELMANN STEPHEN ROBERT; WALL BRIAN D; VADEHRA GEETA SOPHIE; UNIV JOHNS HOPKINS 摘要:The aqueous self-assembly of oligopeptide-flanked Ï€-conjugated molecules into discrete one-dimensional nanostructures is described. Unique to these molecules is the fact that the Ï€-conjugated unit has been directly embedded within the peptide backbone by way of a synthetic amino acid with Ï€-functionality that is compatible with standard Fmoc-based peptide synthesis or by way of a diacid or other bis(electrophile) that can covalently cross-link peptide chains presented on a synthesis support. The peptide-based molecular designs enforce intimate Ï€-Ï€ communication within the aggregates after charge-screening and self-assembly, making these nanostructures attractive for optical or electronic applications in biological environments. In other embodiments, a convenient method to incorporate Ï€-electron units into peptides that assemble into amyloid-like supramolecular polymers is disclosed. Self-assembly manipulates these “electronic peptidesâ€? into delocalized sub-10 nm one dimensional (1-D) nanostructures under compltely aqueous conditions.
