Polymer Brush Gradients Grafted from Plasma-Polymerized Surfaces

Harm-Anton Klok, Tugba Bilgiç Tune

A new method for generating a surface density gradient of polymer chains is presented. A substrate-independent polymer deposition technique was used to coat materials with a chemical gradient based on plasma copolymerization of 1,7-octadiene and allylamine ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Véronique Michaud, Holger Frauenrath, Emmanuel Croisier, Joël Cugnoni, Su Liang, Marijana Mionic Ebersold, Ruben Anton Snellings, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...

Maleimide-Functionalized Thiol Reactive Copolymer Brushes: Fabrication and Post-Polymerization Modification

Harm-Anton Klok, Tugba Bilgiç Tune

Polymer brushes that present side chain functional reactive groups are attractive platforms for the development of functional surface coatings. From the wide spectrum of possible postpolymerization modification reactions, thiol-based conjugation chemistrie ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Marco Sangermano, Federica Sordo

In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...

Charge transfer relaxation in donor–acceptor type conjugated materials

Ursula Röthlisberger, Natalie Renuka Banerji, Mariateresa Scarongella, Andrey Laktionov

The development of conjugated materials bearing electron-rich and electron-poor units along their backbone introduces new possibilities to control functionality for organic electronic applications through charge transfer character in ground and excited sta ...

Ruthenium-catalyzed Atom Transfer Radical Addition Reactions

Kay Severin

Certain ruthenium complexes are potent catalysts for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions, in particular if they are used in conjunction with reducing agents such as magnesium. This short overview summarizes recent develop ...

Ruthenium-Catalyzed Sequential Enyne Cross-Metathesis/ATRA Reactions

Kay Severin, Euro Solari, Gregor Kiefer, Jesus Ruiz

Sequential enyne cross-metathesis reactions of arylalkynes with ethylene followed by atom transfer radical addition (ATRA) with ethyl dichloroacetate or dichloroacetonitrile provide 1,5-dichloropent-2-ene derivatives. The second-generation Grubbs alkyliden ...

Arginine-specific protein modification using alpha-oxo-aldehyde functional polymers prepared by atom transfer radical polymerization

Harm-Anton Klok, Maxime Ayer, Frederik Roman Wurm, Marc Gauthier, Justyna Kowal

The residue-specific modification of peptides and proteins is a powerful strategy for preparing biomolecular-synthetic polymer conjugates with advanced properties. This manuscript aims at expanding the present toolbox of residue-selective protein modificat ...

Side-Chain Peptide-Synthetic Polymer Conjugates via Tandem "Ester-Amide/Thiol-Ene" Post-Polymerization Modification of Poly(pentafluorophenyl methacrylate) Obtained Using ATRP

Harm-Anton Klok, Maarten Danial, Matthew Gibson

Herein the concept of tandem postpolymerization modification as a versatile route to synthesize well-defined, highly functionalized polymers is introduced. Poly(pentafluorophenyl methacrylate) obtained by atom transfer radical polymerization was first modi ...
