摘要
金属有机框架(metal-organic frameworks,MOFs)是一类由金属离子(簇)与有机桥联配体通过自组装连接而成的具有纳米孔穴的超分子晶体材料。它们具有极大的比表面积、可调控的孔径和拓扑结构、良好热稳定性和化学稳定性等优点,在化学传感方面有良好的应用前景。该文综述了近年来MOFs化学传感器方面的研究进展,侧重于光学、电化学、微天平、光电流等类型MOFs传感器的信号传导策略及其在检测挥发性有机物、金属离子、DNA、蛋白质及其它重要生物分子的分析应用。
Metal-organic frameworks(MOFs) are a class of hybrid materials self-assembled from organic bridging ligands and metal ion/cluster connecting points. As nanoporous, supramolecular materials, MOFs have unique chemical and physical properties, such as ultrahigh surface area, tunable structure, and high thermal and chemical stability. These characteristics make MOFs very attractive for chemical sensing. That short-focused article reports on recent efforts and progress in MOFs-based sensors with an emphasis on the design of functional MOFs and signaltransduction strategy, including optical, electrochemical, microbalance, and photoelectroehemical schemes, for analytical applications in detection of volatile organic compounds, metal ions, DNA, proteins, and other important biomolecules.
