| 内容記述 | Photoionization of tricyclazole(5-Methyl-1,2,4-triazolo[3,4-b]benzothiazole: TCA) of typical agricultural chemical was achieved with two-photon two-step excitation by using 266-nm laser pulse irradiation in the presence of cyclodextrins (CDs). Ionization of TCA within the laser flash (5 ns) produced a radical cation of TCA and hydrated electrons. The ionization quantum yield (Φion) of TCA in the presence ofα-, β-and γ-CD calculated to be0.27%,0.21%,0.44%, respectively, and it is due to the property of the TCA/CDs inclusion complex. The Φion of TCA in the presence of CDs (1.0×10-2M)was independent of the fluorescence lifetime. In the case of CD concentration effect, Φion of TCA/β-and γ-CD were dependent on the fluorescence lifetime. Additionally, we observed the different phenomena of florescence spectra of TCA/CDs. Presence results indicate that intramolecular charge transfer state(ICT) of TCA/CDs is significantly related due to confinement by the cyclodextrin nanocavities. These results suggest the possibility of the photolysis of molecular with ICT such as agricultural chemicals in aqueous solution by using TPI of UV light irradiation. | |||||
