Overview
The synthesis and characterization of new photoactive molecular materials are at the heart of the team’s work. The ruthenium nitrosyl complexes, due to their wide range of physicochemical properties, concentrate a large part of our activity.
Theoretical prediction of these properties allows us to efficiently guide the experimenters towards the best synthetic targets. Obtaining nanometric aggregates of these molecular objects is also part of the team’s strategies.
Our interest in these systems lies in their photoreactivity which allows us to consider applications in photodynamic therapy or in optical information storage.

NO photo-release in ruthenium nitrosyl complexes / nano-objects
Nitric oxide (NO) is now recognized for its implications in numerous biological mechanisms, including the fight against cancer and bacteria…
Photo-induced isomerization in ruthenium nitrosyl complexes Ru-NO / Ru-ON commutation
Obtaining materials with an atom or molecule that can be switched into two distinct states can generate storage capacities comparable to those of the DNA molecule, i.e. of the order of a terabyte/cm3.
Applications in the field of health
Given the difficulties encountered by conventional antibiotics in treating certain infections, particularly those caused by biofilms, there is an urgent need to develop new therapies to combat antimicrobial resistance.
Team news
Highlight 2022 Team R
Ruthenium complexes with nitrosyl ligands are used to non-invasively release nitric oxide through light irradiation using the “two-photon absorption” (TPA) technique, and bimetallic complexes exhibit a five-fold higher sTPA value compared to monometallic complexes.
