Fluorescent imidazolium receptors for the recognition of pyrophosphate

Anthracene and binaphthyl derivatives bearing two imidazolium rings, which strongly bind anions and are particularly selective for pyrophosphate, are examined using fluorescence, 1H NMR analysis, and density functional calculations.
