摘要
金属-有机骨架材料(MOFs),是一类由金属节点或者是次级构筑单元与有机配体通过配位键自组装形成的材料,因其丰富的拓扑结构及在多领域的潜在应用而被广泛研究。最近关于块状和纳米颗粒形式的发光MOFs的研究表明,这些材料具有优异的发光性质,可用来检测识别溶剂分子、重金属离子、黄曲霉素、硝基苯类爆炸物以及碘离子等。并且开发高灵敏度、高选择性、快速响应和完全可逆的有毒物质和爆炸物检测传感器,在国土安全、环境安全及其他人道主义关切问题上有着极大的需求。本文主要讨论MOF材料作为荧光传感器的应用研究和发展前景。
Metal-organic frameworks(MOFs)are a class of materials that are formed by metal nodes or secondary building units(SBUs)and organic ligands that are self-assembled through coordination bonds.They have been extensively studied for their rich structural chemistry and potential applications in numerous area.Recent studies on luminescent MOFs in both bulk and nanoparticle forms have shown that these materials possess excellent luminescence emission properties that can be utilized to effectively detect solvent molecules,heavy metal ions,aflatoxin,nitrobenzene explosives,iodide ions and so on.In addition,developing highly sensitive,selective,fastresponding and fully reversible sensors for toxic substances and explosives’detection is in great demand for the homeland security,environmental safety and other humanitarian concerns.This paper mainly discusses the possible mechanisms and development prospects of MOF materials as fluorescent sensors.
