Recherches actuelles

Mes activités portent sur la conception et la synthèse de systèmes π-conjugués auto-organisés. Le contrôle de l’organisation s’effectue le plus souvent par une fonctionnalisation des composés par des chaînes flexibles (ex. chaînes alkyles ou siloxanes) à des positions particulières. Je m’intéresse tout particulièrement à stabiliser les systèmes (macro)moléculaires dans des organisations mésomorphes variées, pour des applications en optoélectroniques.

Une fonctionnalisation plus importante des molécules par des chaînes souples siloxanes, permet de développer des liquides moléculaires fonctionnels, c-à.d. des composés qui se présentent dans un état liquide stable (sans solvant) à température ambiante. Ces matériaux présentent un grand intérêt pour la réalisation de dispositifs optoélectroniques ultra-flexibles et en microfluidique.

Domaines d’expertise:

  • Systèmes auto-organisés (mésomorphes, cristaux liquides…)
  • Liquides moléculaires fonctionnels
  • Matériaux fonctionnels hybrides à base siloxane
  • Molécules et polymères π-conjugués pour l’optoélectronique (semiconducteurs, photovoltaïque organique, diodes électroluminescentes…)
