  名称：

  A bifunctional acridine-based fluorescent sensor: ratiometric sensing of H2PO4− and obvious fluorescence quenching towards HSO4− through a synergistic binding effect of benzimidazolium and urea moieties

  摘要：

  Three tweezer-like fluorescent sensors 1-3 based on acridine fluorophore were designed and synthesized. Anion binding properties of sensors 1-3 were studied by fluorescence, UV-vis, H-1 NMR, and FIRMS. Results showed that the sensor 1, which bears both benzimidazolium and urea groups as binding sites exhibited better anion sensing performance compared with sensors 2 and 3 containing only one kind of binding sites. Especially, it could be used as a dual-responsive selective fluorescent sensor for both H2PO4- and HSO4- via fluorescent bathochromic-shift and fluorescence quenching, respectively. The unique selectivity of sensor 1 towards H2PO4- and HSO4- could be attributed to the synergistic binding effect of benzimidazolium and urea moieties. In addition, the additional hydrogen bond between -OH in H2PO4-/HSO4- and the N on acridine of sensor 1 also played an important role in improving its anion binding affinities. (C) 2013 Elsevier Ltd.

  The synthesis of some novel dicationic acridinophanes has been achieved via an N-alkylation route using benzimidazole, imidazole and benzotriazole as building units. UV-Visible studies revealed the absence of ground-state charge-transfer interactions between the acridine and imidazolium moieties. Electrochemical studies showed that the imidazolium and acridine units modify the characteristic redox
