Soft-landing electrospray ion beam deposition of sensitive oligoynes on surfaces in vacuum

Klaus Kern, Holger Frauenrath, Stephen Schrettl, Tobias Hoheisel, Stephan Rauschenbach, Gordon Rinke

Characterizing the complex structure of such molecules with highly resolving, vacuum-based methods like scanning probe microscopy requires their transfer into the gas phase and further onto an atomically clean surface in ultrahigh vacuum without causing ad ...

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 ...

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

Rosario Scopelliti, Andrzej Sienkiewicz, Holger Frauenrath, Anne-Clémence Corminboeuf, 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 ...

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 ...
