Abstract
A new acridine derivative bearing two imidazolium groups has been synthesized. This chemosensor displayed a large fluorescent quenching effect with pyrophosphate and a unique fluorescent enhancement with H 2PO 4 -. The strong (C-H) +⋯X - hydrogen bonding between the imidazolium moieties and anions is the key interaction for the recognition. The association constant of 1 with pyrophosphate was calculated as 4.9×10 7 M -1. © 2008 Elsevier Ltd. All rights reserved.
