Kinetically Controlled Sequential Growth of Surface-Grafted Chiral Supramolecular Copolymers.

2016

We report a facile strategy to grow supramolecular copolymers on Au surfaces by successively exposing a surface-anchored monomer to solutions of oppositely charged peptide comonomers. Charge regulation on the active chain end of the polymer sufficiently slows down the kinetics of the self-assembly process to produce kinetically trapped copolymers at near-neutral pH. We thereby achieve architectural control at three levels: The β-sheet sequences direct the polymerization away from the surface, the height of the supramolecular copolymer brushes is well-controlled by the stepwise nature of the alternating copolymer growth, and 2D spatial resolution is realized by using micropatterned initiatin…

Facile access to foldable redox-active flavin-peptide conjugates

2021

A convenient approach for the synthesis of foldable redox-active flavin peptide conjugates was established. A model β-hairpin oligopeptide motif was utilized to demonstrate that azidolysine side-chains are readily functionalised with an alkyne-bearing flavine derivative. The folding equilibrium of the peptide backbone as well as the redox behaviour of the flavin moieties remains intact after the conjugation.

Kinetisch kontrolliertes, sequenzielles Wachstum von chiralen supramolekularen Copolymeren auf Oberflächen

2016

Wir berichten uber eine einfache Strategie zur Herstellung supramolekularer Copolymere an Goldoberflachen durch sukzessive Inkubation einer initiatorbeschichteten Oberflache mit Losungen aus gegensatzlich geladenen peptidischen Comonomeren. Ein ladungsreguliertes Wachstum des Polymers verlangsamt die Kinetik der Selbstorganisation in dem Mase, dass kinetisch gehemmte Copolymere im nahezu neutralen pH-Bereich gebildet werden. Auf diese Weise erreichen wir eine Kontrolle der Polymerarchitektur auf drei Ebenen: Die β-faltblattkodierte Peptidsequenz steuert eine Wachstumsrichtung der Polymere senkrecht zur Oberflache, die Hohe der supramolekularen Copolymerbursten wird durch den schrittweisen A…
