Due to the paramagnetic nature of Fe(III), receptor ligand becomes one of the key points in developing fluorescent Fe(III) sensors. We report that a new type of receptor ligands that consist of a polyether capped with two amide groups of N-(rhodamine-6G)lactam, selectively sense Fe(III). Its detection limit for Fe(III) is as low as 10 μM, and its linear range for sensing Fe(III) is 14–69 μM.
