Solubility and Crystallizability: Facile Access to Functionalized pi-Conjugated Compounds with Chlorendylimide Protecting Groups

Rosario Scopelliti, Holger Frauenrath, Jan Cornelius Brauer, Jan Gebers, Stéphane Suarez, Damien Rolland, Roman Niklaus Marty, Luca Cervini

Functional pi-conjugated molecules are relevant for the preparation of new organic electronic materials with improved performance. However, their synthesis is often rendered difficult by their inherently low solubility, and the permanent attachment of solu ...

Two-Fold Odd-Even Effect in Self-Assembled Nanowires from Oligopeptide-Polymer-Substituted Perylene Bisimides

Holger Frauenrath, Robin Nigon, Roman Niklaus Marty, Deborah Leite

Organic nanowires are important building blocks for nanoscopic organic electronic devices. In order to ensure efficient charge transport through such nanowires, it is important to understand in detail the molecular parameters that guide self-assembly of pi ...

Aggregates from Perylene Bisimide Oligopeptides as a Test Case for Giant Vibrational Circular Dichroism

Holger Frauenrath, Roman Niklaus Marty

Vibrational circular dichroism (VCD) spectroscopy has become an excellent tool to study biological nanostructures and biomimetic materials in their functional environment and is thus complementary to otherwise employed diffraction, imaging, and spectroscop ...

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 ...

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 ...

Color conversion films comprising polymer-substituted organic fluorescent dyes

Libero Zuppiroli, Holger Frauenrath, Rolando Ferrini, Stéphane Suarez, 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 ...
