title: Pyridinium-based fluororeceptors as practical chemosensors for hydrogen pyrophosphate (HP2O7(3-)) in semiaqueous and aqueous environments.
abstract: The pyridinium-based fluororeceptor 1 and the sensor bead 2 recognize hydrogen pyrophosphate effectively through the 'Indicator Displacement Assay' (IDA) technique over a series of other anions in aq CH(3)CN (CH(3)CN/H(2)O = 4:1, v/v, pH = 6.5). The sensor bead 2 is also capable of sensing the same anion selectively in pure water.
