基于金属-有机框架的乙酰丙酮荧光传感器的研究进展

乙酰丙酮作为重要的化工原料，常用作分析试剂、有机合成中间体等，但人体长时间暴露在乙酰丙酮中会受到一定程度的伤害。目前已有诸如高效液相色谱法、核磁共振法和质谱法等检测乙酰丙酮的方法，但上述方法需要专业人员及大型仪器，且耗时长、操作复杂，因此迫切需要寻找快速高效的乙酰丙酮检测方法。金属-有机框架(Metal-Organic Frameworks，MOFs)材料因其具有丰富的孔隙结构、孔道可调控、比表面积大等特点，在催化、传感、气体储存和分离等方面有着广泛应用，是当前无机化学领域的研究热点之一。MOFs作为荧光传感器具有成本低、响应快速、灵敏度高和效率高等显著优势，可实现对乙酰丙酮的快速高灵敏检测。本文综述了近十年来MOFs用于荧光传感乙酰丙酮的研究进展，并详细总结了其荧光传感机理。 

Recent progress in acetylacetone fluorescence sensors based on metal-organic frameworks

As an important chemical raw material, acetylacetone is commonly used as an analytical reagent and organic synthetic intermediate. However, when exposed to acetylacetone for a long time, the human body will be hurt to a certain extent. At present, there are many methods to detect acetylacetone, such as high-performance liquid chromatography, nuclear magnetic resonance and mass spectrometry, but the above methods require professionals and large instruments and are time consuming complicated to operate. Therefore, it is urgent to find fast and efficient acetylacetone detection methods. Because of their rich pore structure, adjustable pore channels, and large specific surface area, metal-organic framework (MOF) materials are widely used in catalysis, sensing, gas storage and separation and have become one of the research hotspots in the field of inorganic chemistry. As fluorescence sensors with significant advantages in low cost, fast response, high sensitivity and high efficiency, MOFs can realize the rapid and sensitive detection of acetylacetone. The research progress of MOF-based fluorescence sensing of acetylacetone in the past decade was reviewed, and the fluorescence sensing mechanism were summarized in detail.
