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.

Après un doctorat (1995) et un post-doc (1996) dans le domaine des nanoparticules métalliques, j’ai été recruté en tant que maître de conférences à l’université Paul Sabatier de Toulouse dans l’équipe « Molécules et Matériaux ». Je me suis alors intéressé à la préparation de films minces (par voie gazeuse ou par voie électrolytique) de conducteurs et d’aimants moléculaires. J’ai été nommé professeur à l’université Paul Sabatier de Toulouse en 2010 et j’ai pris la direction de l’équipe « Molécules et Matériaux » en 2012. De 2010 à 2020, j’ai animé la thématique dédiée à la synthèse de nanoparticules de conducteurs moléculaires. En 2021, j’ai rejoint l’équipe « Molécules et Composites pour l’Optique ». Je m’intéresse à la préparation d’agrégats nanométriques de complexes nitrosyles du ruthénium pour des applications en photothérapie dynamique. Je suis auteur ou co-auteur de 91 publications dans des revues internationales, de 3 chapitres d’ouvrages et de 3 brevets. J’assure des enseignements dans les cycles L et M, principalement en chimie générale (cinétique, thermodynamique, électrochimie), en spectroscopie (de vibration et atomique), en chimie des solides et des matériaux ainsi qu’en méthodes mathématiques pour la physique.

XIAO Yue

Equipe R

PhD Student working on antibacterial and wound healing properties of Ruthenium Nitrosyl (Ru-NO) complexes. Yue was born in China, grown up in France.

She completed her undergraduate studies in La Rochelle and her graduate studies in Paris, at Sorbonne University.

Yue enjoys skiing during winter, surfing during summer, and a beer after work when Covid allows it. “Chemistry is not a tool restricted to make carbon-carbon bond. It’s a tool of choice to study life.” – Andrée Marquet (UPMC).

She studies drug-design based on light controlled NO release nitrosyl ruthenium complexes: Antibacterial and wound healing agents in collaboration with LGC and IMRCP (Toulouse). PhD project funded by ANR.
