Abstract

A new fluorescent chemosensor bearing two imidazolium groups as well as two anthracene groups has been synthesized. This chemosensor displayed a highly selective fluorescence quenching effect and a unique excimer peak only with H₂ PO₄^-. The association constant of 1 with H₂ PO₄^- was calculated as >10⁶ M^-1.
