Synthesis and self-assembling of phosphorated heterohelicenes for the preparation of materials with high optical activity

This new topic of the group intends to incorporate chirality in phospholes and their derivatives in order to conceive new molecular materials and to investigate their properties. The synthesis of heterohelicenes bearing a phosphole moiety is under current investigation. The purpose of these inherently chiral molecules is to obtain substances with high optical rotations for the conception of chiral wave guides. These new chiral materials could give rise to practical electro-optic devices (i.e. polarisation rotators). The incorporation of oxazolyle moieties into the phosphole framework is also currently studied and is expected to give new chiral ligands with interesting complexing properties. This would enable to prepare chiral nanoscale materials by chiral supramolecular self-assembling using complexation with metallic ions.
