Abstract

We report the two-photon induced photoisomerization of 3-[1-(1,2-dimethyl-1H-indol-3-yl)-ethylidene]-4-isopropylidene- dihydro-furan-2,5-dione (1), a photochromic compound with λ_max = 385 nm, using 775 nm fs pulses. The resulting photoisomer has a λ_max = 582 nm. The kinetic rate constant for the isomerization reaction was measured at two different intensities (two different powers), showing a quadratic dependence with respect to the pump intensity. Results of pump-probe solution phase experiments and guest/host polymer thin film interferometric imaging studies are shown. A two-photon absorption molecular cross-section σ2 = 10.3×10^-48 cm⁴·s/photon was measured using Z-scan, supporting a two-photon induced isomerization process.
