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.
