| 内容記述 | Two-photon ionization of 2-(9,9'-spirobifluorene-2-yl)-9,9'-spirobifluorene ((Fl2)2) in the presence of cyclodextrin (CD) was investigated by using a 266-nm laser pulse or 266- and 532-nm laser pulses (266*532-nm). Measured photoionization efficiency of (Fl2)2/CD was compared with the previous results obtained by using a 266-nm laser pulse. The ionization yield (Υion) obtained with the 266*532-nm laser was 1.4-2.4 times higher than that with the 266-nm laser, suggesting that photoionization of (Fl2)2 proceeds through stepwise excitation by the 266- and 532-nm laser pulses. Moreover, the Υion of (Fl2)2/CD showed different features compared with those obtained with the 266-nm laser pulse and 266*532-nm laser pulses, respectively. It was suggested that the slope of the transient absorbance given as a function of laser intensity can be attributed to difference in the 2-stepwise ionization processes of (Fl2)2/β-CD and (Fl2)2/γ-CD, and the 3-stepwise processes of (Fl2)2/α-CD for irradiation of (Fl2)2 with the 266*532-nm laser. Consequently, we revealed the external light-stimulation of the molecular machine under UV-A irradiation combined with visible light. | |||||
