A toolbox of oligopeptide-modified polymers for tailored elastomers

Joël Cugnoni, Véronique Michaud, Emmanuel Croisier, Marijana Mionic Ebersold, Holger Frauenrath, Su Liang, 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 ...

A Multi-Step Single-Crystal-to-Single-Crystal Bromodiacetylene Dimerization

Andrzej Sienkiewicz, Rosario Scopelliti, Anne-Clémence Corminboeuf, Holger Frauenrath, Stephen Schrettl, Roman Niklaus Marty, Tobias Hoheisel

Packing constraints and precise placement of functional groups are the reason that organic molecules in the crystalline state often display unusual physical or chemical properties not observed in solution. Here we report a single-crystal-to-single-crystal ...

Materials Taking a Lesson from Nature

Emmanuel Croisier, Holger Frauenrath, Liangfei Tian

Structural biomaterials with their often extraordinary properties and versatile functions are typically constructed from very limited sets of building blocks and types of supramolecular interactions. In this review we discuss how, inspired by nature's desi ...

Development of a robust supramolecular method to prepare well-defined nanofibrils from conjugated molecules

Holger Frauenrath, Roman Niklaus Marty, Liangfei Tian, Ruth Szilluweit

In order to produce materials with tailored structures and functions via supramolecular self-assembly of molecular precursors in a predictable fashion, it is necessary to develop 'supramolecular methods' based on structurally simple 'supramolecular synthon ...

Multi-Set Point Intermittent Contact (MUSIC) Mode Atomic Force Microscopy of Oligothiophene Fibrils

Holger Frauenrath, Liangfei Tian, Ruth Szilluweit

We developed MUSIC-mode atomic force microscopy (AFM) to emulate intermittent contact mode AFM without a feedback loop and in the absence of lateral forces. This single-pass approach is based On maps of amplitude-phase-distance curves and allows the height ...

Color conversion films comprising polymer-substituted organic fluorescent dyes

Libero Zuppiroli, Rolando Ferrini, Stéphane Suarez, Holger Frauenrath, Roman Niklaus Marty

The present invention concerns a color conversion film comprising at least one active layer, said layer comprising an organic fluorescent dye containing a fluorescent core, wherein said dye is substituted with at least one polymer segment. It also concerns ...

Low-Temperature Preparation of Tailored Carbon Nanostructures in Water

Raffaele Mezzenga, Vincent Laporte, Davide Demurtas, Anna Fontcuberta i Morral, Bernt Ketterer, Holger Frauenrath, Tobias Hoheisel, Ruth Szilluweit, Martin Fritzsche

The development of low-temperature carbonization procedures promises to provide novel nanostructured carbon materials that are of high current interest in materials science and technology. Here, we report a "wet-chemical" carbonization method that utilizes ...

Nanostructured Carbonaceous Materials from Molecular Precursors

Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Ruth Szilluweit

Nanostructured carbonaceous materials, that is, carbon materials with a feature size on the nanometer scale and, in some cases, functionalized surfaces, already play an important role in a wide range of emerging fields, such as the search for novel energy ...

Perfluorophenyl-Phenyl Interactions in the Crystallization and Topochemical Polymerization of Triacetylene Monomers

Holger Frauenrath, Rui Xu

A series of symmetrically and unsymmetrically substituted octa-2,4,6-triyne-1,8-diol derivatives with benzoyl, 4-dodecyloxybenzoyl, as well as perfluorobenzoyl substituents were prepared and investigated with respect to their crystal structures and topoche ...
