Fluorescence spectra of Thp in the presence of SBE-β-CD. The concentration of Thp is 5.0 × 10-4 mol/L and concentrations of SBE-β-CD are 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 × 10-2 mol/L from bottom to top in 10:90 (v/v) ethanol/50 mmol phosphate buffer solution. Inset shows fluorescence spectra in the presence of SBE-β-CD concentrations from bottom to top are 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6 and 1.8 × 10-3 mol/L.
