Synthèse et caractérisations de nouveaux penta(organo)[60]fullerènes pour la formation d’assemblages supramoléculaires

Abstract : The unique structure and properties of fullerenes have attracted wide interest especially in electronic and optoelectronic fields. In this context, a variety of mono-and poly-fullerene adducts have been described for theirs interest in the development of new complex materials and supramolecular polymers. Here, we present the synthesis and studies of new donor-acceptor supramolecular polymers based on penta(organo)[60]fullerenes. The perfect regioselectivity of the [60]fullerene pentafunctionalization reaction has provided us a singular conical structure formed by five ethynylaryl fragments. To this structure different electro and/or photoactive fragments (tetrathiafulvalene or zinc-porphyrin) were covalently linked using five simultaneous 1,3-dipolar cycloaddition reactions. The formed host-cavity together with the donor-acceptor properties of these system allow their assembly by supramolecular interactions. We have realized the synthesis of these penta(organo)[60]fullerenes as new donor-acceptor materials and the studies of their remarkable supramolecular arrangement in solution and solid state.
