We have developed simple dual signal (color change and fluorescence ON-OFF) ensemble systems based oil a bis(Dpa-Cu-II) complex I for the detection of PIN in water. Dual signal takes place because of weak binding and fluorescence quenching effect of coordinatively unsaturated Cu-II complex for indicators and replacement of the indicators by more strongly binding PPi. As a consequence, these ensembles show a high selectivity and sensitivity for PPi over various anions including phosphate and its derivatives (AMP, ADP, and ATP) in water.
