Abstract:

A quinoline substituted boron dipyrromethene(BODIPY) based probe(BHQ) was synthesized and characterized by nuclear magnetic resonance spectroscopy(NMR) and high resolution mass spectrometer(HRMS). The probe shows significant enhancement of fluorescence intensity in the presence of Fe3+ in aqueous solution. The probe exhibits fast response, high sensitivity and high selectivity toward Fe3+, while other common metal ions do not show significant interference. The binding between the probe and Fe3+ has been found to be in 1:1 mole ratio based on Job's plot. This result suggests that the probe BHQ has potential application in the determination of Fe3+ ions.
