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 H 2 PO 4 - . The association constant of 1 with H 2 PO 4 - was calculated as >106 M−1.
