Molecules and Composites for Optics (Team R)

LCC

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.
