Abstract

Graphene-based hybrid nanomaterials, which combine the unique properties of each component, have the potential of finding diverse applications in solar cells, sensors and catalysis. Here, we report time-resolved absorption spectroscopic studies on such a hybrid material (consisting of porphyrin molecules
covalently attached to graphene) to resolve the mechanism (energy or electron transfer) underlying the reported [1] fast quenching (< 500 ps) of the porphyrin singlet excited state.
