Dispersions of preexfoliated nanographene (NG) and fused electron donor–acceptor tetrathiafulvalene–perylenediimide (TTF–PDI) enable multifunctional, noncovalently functionalized NG. They were characterized by complementary spectroscopic and microscopic techniques. The design strategy of the chromophoric and electroactive molecular conjugate renders a large and planar π-extended system with a distinct localization of electron-rich and electron-poor parts at either end of the molecular conjugate. Within the in-situ formed nanohybrid, the conjugate was found to couple electronically with NG preferentially through the electron accepting PDI rather than the electron donating TTF and to lead to p-doping of graphene.
