Induced circular dichroism (ICD) capture–release studies of CD complexes of Mg-CP. a ICD spectra of Mg-CP in presence of α-, β- and γ-CDs. b Temperature-dependent ICD spectra of Mg-CP⊃α-CD. Inset shows the changes in the intensity of the ICD band at 355 nm on heating (magenta) and cooling (blue) a solution of Mg-CP⊃α-CD in water between 20 and 90 °C. c Stepwise temperature-controlled quantitative capture of α-CD by an aqueous solution of Mg-CP. Concentration of Mg-CP is 0.06 mg mL⁻¹ and that of α-, β- and γ-CD is 1 × 10⁻³ M
