摘要：

A rhodamine/coumarin-based ratiometric fluorescent Fe3+ sensor has been designed and synthesized. The sensor exhibits a good response to Fe3+ ions with high sensitivity, selectivity and a large shift in the emission spectra (>100 nm), which shows Fe3+-induced FRET OFF-ON and PET ON-OFF behavior.
