Highly selective fluorescent recognition of pyrophosphate in water by a new chemosensing ensemble.
A new chemosensing ensemble that displays sensitive and selective fluorescent recognition of pyrophosphate in water at pH 7.4 has been developed. The ensemble is constructed by a copper complex (receptor) and eosin Y (indicator), the constructed ensemble is capable of highly selectively discriminate pyrophosphate from other common existing anions such as CH(3)COO(-), HSO(4)(-), NO(3)(-), H(2)PO(4)(-), HPO(4)(2-), PO(4)(3-), NCS(-), I(-), Cl(-), Br(-), F(-) as well as some structurally similar carboxylates such as citrate, tartrate, oxalate, malonate, succinate and glutarate.
