摘要：
A new crown ether of 2,13-dibenzothiazol-2'-yldibenzo[b,k]-18-crown-6 was synthesized from 2,13-diformyldibenzo[b,k]-18-crown-6 with 2-aminothiophenol. The binding behavior and the optical properties of the crown ether were examined through UV-visible spectroscopy and fluorescence spectroscopy. When complexed with Na+, K+, Rb+ and Cs+ ions, it led to intramolecular charge transfer and caused the changes of the fluorescence spectra. The protonation of the crown ether was also studied.
