Abstract

Supramolecular donor–acceptor hybrids composed of few-layer graphene as an electron acceptor and phthalocyanine or porphyrin bearing four pyrene entities as photosensitizer donors have been synthesized, and occurrence of ultrafast charge separation in the order of 1011–1012 s−1 due to close proximity of the donor and acceptor entities is demonstrated.
