▎ 摘　　要

The idea of attaching multiple porphyrins to graphene is explored. A charged porphyrin salt is stabilized onto exfoliated graphene by taking advantage of pi-pi* interactions, and a second porphyrin light harvester is anchored through electrostatic interactions with the former. The interactions are capable of allowing electronic communication of the second, electrostatically attached, porphyrin with graphene, effectively quenching its emission. The graphene-porphyrin-porphyrin triad is examined through optical (UV-vis, steady state and time-resolved photoluminescence) techniques, while electrochemistry is employed to study the thermodynamically favored pathways through which the interaction occurs. The porphyrin that is electrostatically stabilized onto the graphene nanoensemble shows lifetimes 1 order of magnitude faster than its pi-pi* stacked analogue suggesting a more efficient pathway.
