摘要

基于配-金属电荷转移过程，首次合成了一种新型荧光La@ZrMOF纳米材料，用于方便、直观地检测乙烯利（ETH）。随着ETH浓度的增加，荧光信号逐渐增强，颜色由无色变为蓝色。检测限为0.03 mg/L，检测时间为75 min。还设计了一种基于纸张的快速和视觉测定ETH的方法，使其能够有效地用于各种实际产品，如苹果，梨和西红柿。事实证明，该方法简单，易于使用，灵敏度高，具有进一步应用于ETH检测的潜力。图形抽象

Convenient and visual ethephon detection in fruits by enhanced fluorescence of metal–organic framework

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.
