摘要：

Sodium anthranilate-modified beta-cyclodextrin (1) has been prepared as a sensor for detecting organic compounds including terpenoids and steroids. 1 shows a pure monomer fluorescence whose intensity is increased or decreased upon addition of the guest species examined. In this system, the sodium anthranilate moiety acts either as a spacer, which enables the cyclodextrin to form a 1 : 1 guest complex by narrowing the beta-cyclodextrin cavity or acts as a hydrophobic cap. 1 shows a higher sensitivity for terpenoids than for steroids, but has a higher selective molecular recognition ablity for steroids than for terpenoids.
