Ratiometric probes for hydrogencarbonate analysis in intracellular or extracellular environments using europium luminescence†
Abstract
A series of six, cationic, zwitterionic and anionic Eu complexes has been examined for the analysis of hydrogencarbonate concentration in the intracellular and extracellular ranges; an anionic complex incorporating three glutarate residues and a sensitising acridone
