title: A ratiometric fluorescence sensor for Fe(3+) based on FRET and PET processes.
abstract: 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.
