We are developing a novel hybrid class of adsorbent for the rapid uptake of and high affinity for hazardous chemicals in contaminated air or water is presented.  These novel adsorbent materials are designed to offer several functional advantages, including targeted adsorption, high capacity, and reusability through a rapid thermal release, without sorbent degradation. This is accomplished by leveraging known metal organic frameworks (MOF) as a stable scaffold for our custom sorbent moieties for capturing analytes via hydrogen bond formation. These sorbent moieties are attached directly to the organic linker of the MOF scaffold and occupy a portion of the pores that are iconic of the MOF structure. The resultant functionalized MOF (fMOF)’s sorbent capabilities are characterized using breakthrough analysis, quartz crystal microbalance, and infrared spectroscopy. fMOF formation will be confirmed using NMR, pXRD, and by measuring the surface area of the MOF before and after modification. Grafting the sorbents onto the MOF scaffold eliminates some self-binding between the current sorbent molecules which limits the adsorbing capacity. These capabilities are compared with the native sorbents’ properties and those of the native MOFs which have been reported to have their own sorbent properties.
