γ-Cyclodextrin with a sodium anthranilate moiety (1) has been prepared as a sensing molecule for organic compounds including terpenoids and bile acids. The sensing and host-guest complexation properties are discussed here in comparison with those of β-cyclodextrin with a sodium anthranilate moiety (2) and γ-cyclodextrin with two sodium anthranilate moieties (3). Compound 1 shows a pure monomer fluorescence with an intensity which increases upon the addition of guest species. The extent of fluorescence variation with a guest is used to determine the sensing factor (ΔI/ I0) of 1 for a guest. Compound 1 recognizes terpenoids better than 3 and bile acids better than 2.
