A rhodamine–naphthalimde dyad capable of discerning Fe3+and Cr3+ions in aqueous samples is synthesized and its application in live cell imaging is demonstrated.

and stacking interactions of the dyes. Study of two control receptors containing either one dye or methyl amide groups instead of amides, revealed that electrostatic and hydrogen bonding interactions contribute the most to affinity and selectivity of receptors. The receptors can detect sulfate in a 1:1 THF–buffer mixture in pH window 3.6–4.5 demonstrating up to 7‐fold fluorescence enhancement. To the
