A fluorescent chemosensor for relay recognition of Fe3+ and PO43− in aqueous solution and its applications

A fluorescent chemosensor for relay recognition of Fe3+ and PO43− in aqueous solution and its applications
A novel fluorescent probe XDS based on 4-methylumbelliferone and 2-picolylamine platforms has been designed and synthesized, which behaves fast relay recognition of Fe3+ and PO4 3− via a fluorescence “on−off−on” response signal. Probe XDS exhibited very high sensitivity and unique selectivity for Fe3+ over other common metal ions, and the detection limit of was 3.2 × 10−7 M. Moreover, the addition of the PO4 3− ions could cause the recovery of fluorescence. This relay recognition feature of probe XDS has potential applications in the determination of trace amount of Fe3+ and PO4 3− in environmental systems. Interestingly, fluorescence imaging experiments demonstrated that the probe XDS can also be used to monitoring the intracellular Fe3+ in RAMOS cells.
