Pyrophosphate-Selective Fluorescent Chemosensor at Physiological pH:  Formation of a Unique Excimer upon Addition of Pyrophosphate

We report a new fluorescent chemosensor that displays an excellent selectivity for pyrophosphate over adenosine triphosphate or phosphate in 100% aqueous solution. A unique fluorescent change was observed upon formation of a 2+2 excimer of the chemosensor.
