Abstract

An ESIPT-based novel fluorescent chemosensor, 1,8-anthraquinonylcalix[4]monocrown-6 (1), which displayed a selective fluorescent change with In3+ among various metal ions, was rationally designed and synthesized. Upon the addition of In3+, the probe displayed a fluorescence decrease at 625 nm, at the same time, an increase of the band centered at 535 nm was observed. This sensing process was also proved by the 1H NMR titration and electrochemical tests.
