Self-Assembly in water of C fullerene into isotropic nanoparticles or nanoplatelets mediated by a cationic amphiphilic polymer.

Hypothesis: To disperse high concentration of C fullerene in water, we propose to use an emulsification-evaporation process in the presence of an amphiphilic polymer whose chemical structure has been chosen for inducing specific interaction with fullerene The viscosity enhancement provided by self-assembly of the amphiphilic polymers in water should result in high stability of the suspensions. The organic solvent has also to been chosen so as to maximize the initial fullerene concentration.

Experiments: The concentrations of polymer and fullerene, the solvent type and the volume fraction of the organic phase have been varied.

Synthesis and self-assembly of a penta[60]fullerene bearing benzo[]perylenetriimide units.

A benzo[]perylenetriimide (BPTI) derivative bearing a terminal azido group on the expanded π-conjugated backbone has been synthesized and characterized. This promising photo- and electroactive BPTI motif has been used to obtain an original penta(organo)fullerene as a promising multi-electron acceptor system. Our studies show its self-assembly resulting from aggregation π-π stacking interaction in solution and in the solid state.
