Chimie organique

Sugars to control ligand shape in metal complexes: conformationally constrained glycoligands with a predetermination of stereochemistry and a structural control.

In coordination chemistry, ligand shape can be used to tune properties, such as metal selectivity, coordination number, electronic structure, redox potential, and metal center stereochemistry including coordination helicates formation, and also to…

Synthesis of organic nanoparticles in a 3D flow focusing microreactor

In this paper, we present the synthesis of organic nanocrystals in a 3D hydrodynamic focusing device through a non-solvent crystallization process. This microreactor was designed in order to control the supersaturation level, while manipulating…

Pi-stacking functionalization through micelles swelling : Application to the synthesis of single wall carbon nanotube/porphyrin complexes for energy transfer

We report on a new, original and efficient method for p-stacking functionalization of single-wall carbon nanotubes. This method is applied to the synthesis of a high-yield light-harvesting system combining single-wall carbon nanotubes and porphyrin…

Selective chemical sensors based on fluorescent organic nanocrystals confined in sol-gel coatings of controlled porosity

We have developed chemical sensors based on strong modifications of rubrene nanocrystals fluorescence decays under different chemical surroundings. These nanocrystals were grown in silicate sol-gel thin films. To improve the nanosensors selectivity, we…

Photoinduced Cation Translocation in a Calix[4]biscrown: Towards a New Type of Light-Driven Molecular Shuttle

The photophysics of a ditopic receptor of potassium ion consisting of a 1,3-alternate calix[4]biscrown with a merocyanine dye (DCM) inserted into each crown is reported. Thanks to the large difference between the binding affinity for one and two…
