Abstract

A novel artificial anion chemosensor 1 based on 2,2'-di(4-nitrophenylurea-β-N-yl)-1, 1'-binaphthyl is designed and synthesized for sensing anions including halide ions and oxoanions. The fluorescent emission of the binaphthyl of receptor 1, forming the hydrogen bonding with anions as the sensing mechanism, is monitored in DMSO for detecting anions. In brief, while most of the anion chemosensors are switch-off fluorescent chemosensor, or non-fluorescent sensor, receptor 1 exhibits obviously the switch-on emission during the complexation with H(2)PO(4)(-). © Springer Science+Business Media, LLC 2011
