Abstract
4-Hydroxy-5-isopropyl-2-methylisophthalaldehyde anchored rhodamine B derivative, RDDFT experiences Fe3+ assisted inhibition of photoinduced electron transfer (PET), chelation-enhanced fluorescence (CHEF) and fluorescence resonance energy transfer (FRET) process in aqueous buffered acetonitrile media. RDDFT is an excellent colorimetric Fe3+ probe that undergoes ratiometric fluorescence change to recognize and determine traces of Fe3+ in presence of Fe2+ in real sample, thus allowing speciation studies of iron. It detects as low as 2×10−8M Fe3+ with an association constant, 3.7025×106M−1. Common ions do not show any significant interference in the detection of Fe3+ ion. RDDFT efficiently images intracellular Fe3+ in HeLa cells under fluorescence microscope. DFT studies strongly support experimental findings.
