Single-walled carbon nanotubes have been functionalized with derivatized porphyrins (see Figure). The photoexcited state properties of the nanotube-tethered porphyrin moieties are investigated via steady-state and time-resolved fluorescence methods. Intramolecular energy-transfer quenching of porphyrin fluorescence by the tethered nanotube occurs in the sample with a longer tether, but no fluorescence quenching is observed in the sample with a shorter tether.
