Simple but effective way to sense pyrophosphate and inorganic phosphate by fluorescence changes

Abstract

(Graph Presented) A new fluorescent chemosensor based on the acridine-Zn(II) derivative effectively recognizes pyrophosphate and inorganic phosphate at pH 7.4. Acridine derivative 1 displayed a fluorescent quenching effect with pyrophosphate; on the other hand, a large fluorescent enhancement was observed with inorganic phosphate. © 2007 American Chemical Society.
