For the first time a novel fluorescent La@ZrMOF nanomaterial was synthesized for the convenient and visual detection of ethephon (ETH) based on the ligand-metal charge transfer process. The fluorescence signal gradually enhanced as the concentration of ETH increased, accompanied by a change in the color from colorless to blue. The assay can be completed within 75 min with a detection limit of 0.03 mg/L. A paper-based approach for the rapid and visual determination of ETH has also been devised, enabling the efficient used in a variety of actual products, with apples, pears, and tomatoes as examples. It proved to be simple, easy to use, and sensitive, and has the potential for further uses of ETH detection.
首次合成了一种新型荧光La@ZrMOF纳米材料，用于基于配体-金属电荷转移过程方便、可视化检测乙烯利（ETH）。随着ETH浓度增加，荧光信号逐渐增强，同时颜色从无色变为蓝色。该检测方法可在75分钟内完成，检测限为0.03mg/L。还设计了一种基于纸的快速可视化测定ETH的方法，以苹果、梨和番茄为例，使其能够有效地应用于各种实际产品中。结果证明该方法简单、易用且灵敏，具有进一步用于ETH检测的潜力。
