摘要：

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 PO43- 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 x 10(-7) M. Moreover, the addition of the PO43- 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 PO43- in environmental systems. Interestingly, fluorescence imaging experiments demonstrated that the probe XDS can also be used to monitoring the intracellular Fe3+ in RAMOS cells.
