Welcome to the Laboratory of Macromolecular and Organic Materials

The Laboratory of Macromolecular and Organic Materials is part of the Institute of Materials at EPFL. We pursue an interdisciplinary research program at the interface of synthetic chemistry, supramolecular self-assembly, and materials science. Our research interests revolve around the intricate balance of order and disorder in materials as a tool to control structure formation on the supramolecular, nanoscopic, or microscopic length scale. We ultimately use this concept to guide chemical reactivity of metastable molecular precursor for carbon nanomaterials, control electronic properties in organic semiconductor nanostructures, or tailor the bulk mechanical properties in supramolecular materials. In all of our investigations, we complement a chemistry-driven interest in structure formation on the supramolecular level with a broader materials science perspective, investigating structures of macromolecular and organic materials at all length scales, with an attention to bulk properties, applications, and devices.

Functional Carbon Nanomaterials at Room TemperatureCarbon nanomaterials offer intriguing perspectives for applications in emerging technologies such as hydrogen storage, lithium storage, transition metal free catalysis, or photovoltaics. A better control over surface chemistry, carbon structure, nanoscopic morphology, and microstructure would be desirable but has so far been excluded by the high-energy processes employed for their (…)

Organic Electronic Materials with 1D and 2D NanostructuresOrganic nanowirefs are model systems for the investigation of charge transport in organic semiconductors under nanoscopic confinement, and may serve as potential building blocks for integrated circuits in the future. However, reliable structure-property relationships between the molecular parameters, the intermolecular π–π interactions, the nature of the charge carriers, (…)

Supramolecular networks that make use of specific non-covalent interactions furnish elastomer materials with superior processing and self-healing properties. However, they typically lack the hierarchical structure formation on different length scales observed in biomaterials that could be employed to tailor their mechanical properties. We prepared novel supramolecular materials based on oligopeptide-modified polymers that gave rise to (…)
