Supramolecular assembly of graphene with functionalized poly(fluorene-alt-phenylene): The role of the anthraquinone pendant groups

Abstract

Hybrid materials composed of graphene and conjugated poly(fluorene-alt- phenylene) endowed with redox-active anthraquinone moieties are prepared. Remarkable changes in the electronic properties of the polymer are observed. Effective interactions among the pendant anthraquinone and graphene, likely due to π-π stacking, are confirmed.
