 note = {Dansyl-modified β-, γ-cyclodextrins (1 and 2) have been prepared as a sensor for detecting bioactive-organic compounds such as steroids and alkaloids. 1 shows pure monomer fluorescence whose intensity is decreased upon addition of guest species. However, 2 shows two types of pure monomer fluorescence, that is, one is the same for the case of 1, the other is whose intensities is enhanced upon addition of guest species. This guest-induced variation in the fluorescence intensity suggests that the dancylglycine moiety acts as a spacer which enables the cyclodextrin to form 1 : 1 host complexing by narrowing the large γ-cyclodextrin cavity. The value △I/I°, where I and ro are fluorescence intensities in the presence and absence of a guest and △I is 1°-I is fluorescence parameter. 1 exhibits higher selective and sensitive molecular recognition ability for steroids and alkaloids except for lithocholic acid than does 2.},
