| Research Abstract |
Precisely-controlled metal array fabrication was accomplished through self-assembly of metalated amino acids and related peptides in which functional transition-metal complexes conjugate to the α-side chain of amino acids. The chemically and physically robust Pd- Pt- and Ru-complex-bound amino acids gave nanometer-scale controlled metal array fabricated by ultrasound-induced gelation or micelle formation. Control of metal sequence was accomplished by condensation of these Pd- and Pt-bound amino acids by chronological ordering of the amino acid condensation. Supramolecular-based self-assembly of Pd- and Pt-bound dipeptides also gave nanometer-scale regulated array of Pd- and Pt-complexes. The resulting Pd-, Pt- and Ru-array acts as efficient recyclable supramolecularcatalyst in aqueous conditions toward various types of organic reactions such as alkyne transformation, cross-coupling reactions, and oxidations of alcohols.
