A naked-eye sensing ensemble for the selective detection of citrate--but not tartrate or malate--in water based on a tris-cationic receptor.
Citrate 3 can be selectively detected in aqueous solvents even in the presence of malate or tartrate using a naked-eye detection system based on the complex between tris-cation 1 and carboxyfluorescein 2.
