A rhodamine/coumarin‐based ratiometric fluorescent Fe 3+ sensor has been designed and synthesized. The sensor exhibits a good response to Fe 3+ ions with high sensitivity, selectivity and a large shift in the emission spectra (>100 nm), which shows Fe 3+ ‐induced FRET OFF–ON and PET ON–OFF behavior.
