“…Over the past decades, room temperature (RT) synthesis of MOFs has been the focus of researchers due to its low energy consumption, mild synthesis conditions, and ease of endowing MOFs with unique properties. − A series of divalent and trivalent metal MOFs, like the ZIF and MIL (Al, Fe), − were synthesized by the RT synthesis strategy. Meanwhile, due to the great application prospects of tetravalent MOFs like UiO-66 with low toxicity and high chemical stability, their RT synthesis has been advanced in recent years. − The reported RT syntheses of MOFs mainly relied on specific reactants or additives to promote nucleation, which was costly and time-consuming.…”

Simple and rapid synthesis of multifunctional metal–organic frameworks (MOFs) at room temperature (RT) with their multifunction controllable is still appealing for further expansion of the practical applications of MOFs. Herein, in this work, rapid RT synthesis of a multifunctional UiO-66(Ce) [M-UiO-66(Ce)] with both oxidase-like activity and fluorescence emission properties was facilely achieved within 15 min through a straightforward reactant concentration modulation and self-catalytic postmodification strategy. Appropriate concentrations of cerium ammonium nitrate or 1,4-benzenedicarboxylic acid (BDC) were beneficial for the synthesis of UiO-66(Ce) with better crystallization. During the postmodification process, through regulation of the self-photocatalysis of UiO-66(Ce), a high conversion rate from BDC to BDC-OH of up to 14% can be obtained, resulting in a significantly enhanced fluorescence signal of M-UiO-66(Ce) within 2 min. Moreover, M-UiO-66(Ce) enabled the accurate and reliable detection of tetracycline (TC) in real samples. Besides, the colorimetric and fluorescence modes complemented each other, expanding the linear range of TC detection and exhibiting its great potential for practical applications. This work provides new insights for the convenient and rapid synthesis of multifunctional materials based on MOFs, which is favorable for promoting the large-scale preparation of MOFs and their practical application in on-site environmental pollutant sensing.
