Our research deals with the development of various π-conjugated heterocyclic push-pull systems and the study of their physical and chemical properties. Our investigations have shown the existence of structure-property relationships in these heterocyclic compounds making them excellent building-blocks to engineer π-conjugated organic and organometallic moleculars systems, with applications in dye-sensitized solar cells, luminescence and non-linear optics.

Synthesis, studies of electrochemical, linear/nonlinear optical properties of heterocyclic organic and organometallic D-π-A “push-pull” chromophores incorporating in particular pyranylidene ligands as pro-aromatic donor groups (D), diazine rings as electron-withdrawing groups (A), and various functional organic or organometallic groups (Pt, Ru..) as π-linkers separating the donor and the acceptor groups.
