Transient conductivity and absorption profiles of the homotropic and coassembled nanotubes of 1 and 2. (A) Plots of φΣμmax versus f1. Transient conductivity (φΣμ) in FP-TRMC is given by multiplication of photocarrier generation yield (φ) and sum of charge carrier mobilities (Σμ) (32). (B) FP-TAS at 25 °C of a cast film of the coassembled nanotube with f1 = 10% upon photoirradiation at 355 nm (photon density, 3.6 × 1015 cm−2). (Inset) FP-TAS at 25 °C of a cast film of the homotropic nanotube of 2. Transient species arising from C60 were not observed because of a detection limit of the spectroscope. (C) Normalized FP-TRMC (orange) and FP-TAS (blue; λ = 605 nm) profiles of a cast film of the coassembled nanotube with f1 = 10%, upon photoirradiation at 355 nm (photon density, 1.2 × 1015 cm−2). (D) Plots of Σμ1D for a cast film of the coassembled nanotube with f1 = 10% versus photon density.
