N2 - Assembly of a new functional organic linker, (dimethyl 4-(carbaldehyde oxime) pyridine-2,6-dicarboxylate, L1), with europium ions modified Uio-67 leads to Uio-Eu-L1, which is shown to be a new molecular-based probe with high sensitivity and selectivity for ClO−. The detection limit is calculated to be as low as 16 nM. To our knowledge, this is the first report of a sensitive europium sensor for ClO− established on the oxime isomerization reaction. The nature of organic L1 sensitizer within the complex has been demonstrated to control the photoluminescence effectively. The “off-on” signal changes can be realized by oxidative deoximation reaction induced recognition of hypochlorite. More strikingly, both continuous-mode lanthanide emission (steady-state photoluminescence measurement) and time-gated luminescence detection are collected in the presence of several interference organic dyes. This remarkable optical feature will allow easy spectral and discrimination of their emission bands from separation of noisy signals.
