Metal-Organic Frameworks as Sensors: A ZIF-8 Based Fabry-Perot Device as a Selective Sensor for Chemical Vapors and Gases

摘要

Permanently microporous metal-organic framework (MOF) materials have attracted considerable attention on account of their large internal surface areas, uniform channels, (sub)nanometer-sized cavities, thermal stability, and chemical tailorability. Among the potential applications for which proof-of-concept reports have proliferated are gas storage, chemical catalysis, and small-molecule separations. At first glance MOFs would also appear to be attractive for chemical sensing. Nevertheless, reports of MOF-based sensing are comparatively few.
