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

J Org Chem. 2005 Nov 11;70(23):9603-6. doi: 10.1021/jo0509657.

Abstract

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