摘要：

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(2)PO(4)(-). The strong (C-H)(+)center dot center dot center dot 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 4.9x10(7) M(-1). (c) 2008 Elsevier Ltd. All rights reserved.
