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.
