Abstract :
The interaction of Rose Bengal (RB) in aqueous solution of LiClO4 0.1 M with α-cyclodextrin (α-CD), hydroxypropyl-β-cyclodextrins (HP-β-CD) and hydroxypropyl-γ-cyclodextrins (HP-γ-CD) were studied by spectrophotometric measurements. The presence of Induced Circular Signals and the results of the analysis of the modifications in the absorbance spectra of RB produced by the presence of CDs in solution indicate that RB forms inclusion complexes only with HP-β-CD and with HP-γ-CD.
