Recherches actuelles

Mes activités portent sur la conception et la synthèse de systèmes moléculaires et macromoléculaires pi-conjugués d’organisation contrôlée. 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. 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. Les domaines d’application visés couvrent principalement l’optoélectronique.

Domaines d’expertise:

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