Absorption and fluorescence spectral studies. (a,b) Absorption (a) and fluorescence (b) spectra of DOFL (20 μM) at pH 7.5 at different concentrations of CB7. [CB7]/μM: (1) 0.0, (2) 2.0, (3) 6.0, (4) 16.0, (5) 35.7, (6) 74.6 and (7) 116.5. The respective absorption and fluorescence titration curves are shown in the insets; the solid line represents the fitted curve according to a 1:1 complexation model.
