Current Research

The green fluorescent protein provides a wellspring of bio-inspiration for luminescence’s property tuning or switch, since the modification of the cavity embedding a fluorophore triggers its emission tuning on 100 nm scale without changing the fluorophore structure. Such impressive luminescence control highlights the importance of the supramolecular environment in photophysical features. Therefor we are willing to explore the interface between supramolecular chemistry, coordination chemistry, photophysics and chirality, in order to achieve coordination complexes emission or chiroptic properties switch triggered by its environment tuning. Such achievement may raise plethora’s applications in probing, light emitting devices or bio-imaging.

Our activity is transdisciplinary and harness various chemistry fields and skills such as organic synthesis, coordination complexes synthesis, spectroscopic characterisation methods (NMR, EPR), photophysical measurements and chiroptic (CD).

Key words
