Research topics:

Research tpoics are oriented toward synthesis, reactivity and study of the properties of organometallic biphenyl (C^C)-based gold(III) complexes associated with different ligands for various applications:

1) Applications in anticancer therapy
We have developped a family of complexes [ (C^C)Au(N^N) ]+ (where (N^N) stands for a bipyridine, phenanthroline or dipyridylamine). We demonstrated the substitution of the N^N ligand in the presence of cycteine, histidine and glutathion as well as the redox stability of the [ (C^C)Au ]+ scaffold. Our current research are oriented toward new families of complexes using more stable chelates and hemilabile ligands. The mechanisms of action of the most promissing candidates are also investigated.

2) Ligand dissociation studies (in collaboration with CSOB team)
We have synthetized a family of complexes bearing variously substituted pyridine ligands and established a direct methodolgy for measuring the dissociation energy of these ligands by mass spectrometry using a HCD collisionnal setup. We showed the relationship between the pka values and the disociation energies of the ligands and correlated the dissociation energies of the pyridine ligands with the catalytic activities of the complexes enabling the optimisation of the catalytic properties of these complexes.

3) Studies of the luminescence properties (in collaboration with Matteo Mauro, UniStra)
Cationic diphosphine-based complexes have showed solid state photoluminescence properties (with quantum yields up to 39 %). These complexes have been used for the fabrication of light-emitting electrochemical cells (LECs) with an external quantum efficacy up to 1 % establishing the first proof-of -concept of the used of Au(III) complexes for LEC device fabrication.
