Synthesis And Self-Assembly Of A Penta[60]Fullerene Bearing Benzo[Ghi]Perylenetriimide Units

A benzo[ghi]perylenetriimide (BPTI) derivative bearing a terminal azido group on the expanded pi-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 via pi-pi stacking interaction in solution and in the solid state.
