"Click"-functionalization of [60]fullerene and graphene with an unsymmetrically functionalized diketopyrrolopyrrole (DPP) derivative.

A synthetic strategy is developed that allows for the facile functionalization of carbon nanostructures thus providing the possibility of comparing the striking different optical and electrochemical properties of ensembles based on the diketopyrrolopyrrole (DPP) chromophore covalently attached to either [60]fullerene or graphene.
