| 内容記述 | We investigated the two-photon ionization (TPI) of Pyrene (Py) in the presence of cyclodextrins (CDs) by using 266-nm laser pulse irradiation. The formation of the incorporation complex of Py/CD was confirmed by 1H NMR measurement. TPI of Py within the laser flash (5 ns) generated a radical cation of Py and hydrated electrons. The ionization quantum yield (Φion) of Py in the presence of α-CD and γ-CD (1.0 × 10-2 M) was calculated to be 64.6 ±1.1%, 0.5 ± 0.1%, respectively. On the other hand, the Φion of Py could not calculated in the presence of β-CD. We concluded that these results were attributed to the decrease of the concentration of singlet excited state by excimer formation and stabilization energy arising from solvation, which was affected by the area of Py protruding from the cavity of the CD. When the concentration of CD was lowered to 1.0 × 10-3 M, the Φion of Py was affected by the fluorescence lifetime, the stabilization energy of salvation, and the excimer formation. As a result, we found that the TPI of Py in the presence of CD were influenced to the fluorescence lifetime, the stabilization energy of salvation, and the excimer formation. | |||||
