The supramolecular chemistry team’s research activities are in the field of sustainable chemistry, at the interface of two disciplines: organic synthesis and supramolecular chemistry. They contribute to the development of more environmentally friendly chemical processes by developing unconventional synthesis methods (ultrasound, microwave) as well as methods for detecting or remedying pollutants and encapsulating bioactive compounds.
Moreover, since the applications associated with cage molecules are largely conditioned by the stability of the complexes formed with the substrates, understanding the mechanisms involved during recognition is essential for the “design” of new compounds and is therefore a strong focus of our academic research. In this framework, we develop innovative characterization methods (optical and NMR spectroscopy, headspace, isothermal titration microcalorimetry), which we confront with the simulation of complexes by molecular mechanics and quantum mechanics.
The application of the supramolecular buildings thus formed is then carried out along two main axes:
Remediation and detection of organic and inorganic pollutants
Among the remediation processes currently available, one of the main limitations remains the low solubility of hydrophobic organic compounds in water. Our research work consists in developing innovative methods adapted to hydrophobic organic compounds (VOC, POP…) and based on the complexing and solubilization properties of cyclodextrins or biosourced solvents.
New organic and/or hybrid materials are obtained by combining fluorescent cage molecules and silicic matrices and, with the aim of trapping and detecting gaseous pollutants (VOC) or metallic cations such as Fe(III). The development of these structures requires, among other things, sol-gel processes, particularly for the production of organized silica.
Encapsulation of compounds of interest (aromas, essential oils, active ingredients)
Encapsulation is a technique to trap liquids or solids in an envelope. Cyclodextrins can thus protect active ingredients against physical degradation, chemical degradation or to allow controlled or prolonged release of active ingredients. Our work consists in characterizing the complexes thus formed in solution (UV-visible, headspace, ITC, NMR) or in solid phase (DSC, IR) and in studying the effect of encapsulation on the physicochemical and/or biological properties of the guest.
Our sonochemical synthesis expertise has been put to good use in an emerging area:
Valorisation of biomass
This research theme aims to develop, from products derived from Linen (fibre, mucilage), a base of biosourced compounds (resins, adhesives, binders) for the formulation of new materials. It is part of a partnership with the Lin regional sector. With a view to possible industrial upgrading, semi-pilot sonochemical reactors are being developed for the production of high-quality fibres and the functionalization of biomass.
