a, Global kinetic traces of differential photoconductivity recorded for spiro-NG (orange) and F-spiro-NG (green) thin solid films upon exposure to 355-nm pulses at 9 × 1014 photons cm−2 under ambient conditions. b, Kinetic traces of photoconductivity (green) and transient optical absorption at 430 nm (averaged 420–440 nm, red) recorded for an identical F-spiro-NG film upon exposure to 355 nm at 9 × 1014 and 2.1 × 1016 photons cm−2, respectively. c, TA spectra recorded immediately (0–0.5 µs, red) and at 4 µs (4–4.5 µs, orange) after pulse exposure. mO.D., mili optical density; μO.D., micro optical density.
