Highly effective fluorescent and colorimetric sensors for pyrophosphate over H2PO4- in 100% aqueous solution

This study demonstrated that Zinpyr-1 center dot Zn2+ acts as a fluorescent and colorimetric sensor for pyrophosphate at pH 7.4. In addition, Zinpyr-l center dot Cu2+ and DIARB-1 center dot Cu2+ complexes were found to act as selective fluorescent sensors for pyrophosphate. Furthermore, the chemosensors Zinpyr-1 center dot Zn2+ and Zinpyr-1 center dot Cu2+ show highly selective and ratiometric fluorescence changes for pyrophosphate compared with H2PO4-.
