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 ››

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 ››

When self-assembly meets biology: luminescent platinum complexes for imaging applications
