Facile synthesis of oligoyne amphiphiles and their rotaxanes

Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Martin Fritzsche, Ruth Szilluweit, Emmanuel Romaric Contal

Carbon-rich organic compounds containing a series of conjugated triple bonds (oligoynes) are relevant synthetic targets, but an improved access to oligoynes bearing functional groups would be desirable. Here, we report the straightforward synthesis of two ...

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 ...

Low-Temperature Preparation of Tailored Carbon Nanostructures in Water

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

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 ...
