Enhancing 2D self-assembly on graphene by chemical functionalization

The research labs headed by Marco Cecchini and Paolo Samorì in ISIS have recently demonstrated that the chemical functionalization of a prototypical PAH (coronene) by perchloro substitution significantly enhances its propensity to form a self-assembled monolayer on graphene. By using a combination of computational and experimental techniques, we showed that perchlorination enhances coronene … Continue Reading ››

Graphene-based Remote Controlled Molecular Switches

"This paper essentially gives an additional remote control to a graphene-based electrical device simply by the exposure to light at specific wavelengths." says Prof. Samorì "This is the first step towards the development of graphene-based multicomponent materials and their use for the fabrication of multifunctional devices - if you imagine a sandwich-like multi-layered structure with … Continue Reading ››

Chiral resolution by shear flow

Thomas Hermans and his team (Non-equilibrium complex systems laboratory) recently developed a novel method for chiral separation without the use of any stationary phase. In fact, this resolution relies on the opposite behavior of two enantiomers in a well-defined shear flow. The preliminary results led to a valorization project financed by SATT Conectus … Continue Reading ››

Optically switchable transistors

Researchers from the Université de Strasbourg (France), in collaboration with the Humboldt-Universität zu Berlin (Germany), Stanford University (USA) and the Université libre de Bruxelles (Belgium), demonstrated that high-performance optically switchable field-effect transistors can be developed by blending photochromic molecules with small organic semiconducting molecules. Such multifunctional organic devices are considered as key elements … Continue Reading ››

Prof. Ebbesen awarded Kavli prize!

THOMAS W. EBBESEN – Physical chemist and director of the University of Strasbourg Institute for Advanced Study, Strasbourg, France. Upending accepted theory, he discovered that light could be transmitted very efficiently through holes smaller than its own wavelength with the involvement of surface plasmons, the interaction of light with electron waves on metal … Continue Reading ››

Graphene–organic composites for electronics: optical and electronic interactions in vacuum, liquids and thin solid films

DOI: 10.1039/C3TC32153C (Feature Article) J. Mater. Chem. C,2014, 2, 3129-3143

Graphene exhibits exceptional mechanical, optical and electrical properties that are unfortunately accompanied by poor processability and tunability of its properties. The controlled interaction of graphene with tailor-made organic semiconductors (OSs) can offer a solution to solve these two … Continue Reading ››
