γ-Cyclodextrin with a sodium anthranilate moiety (<b>1</b>) 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 (<b>2</b>) and γ-cyclodextrin with two sodium anthranilate moieties (<b>3</b>). 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 (Δ<i>I</i>/ <i>I</i><sup>0</sup>) of <b>1</b> for a guest. Compound <b>1</b> recognizes terpenoids better than <b>3</b> and bile acids better than <b>2</b>.
