A critical review of the literature on metal-organic frameworks (MOF) as chemical sensors is presented. Functional groups on the surface may nucleate MOF growth in a specific crystallographic direction, leading to preferentially oriented films. Lan and co-workers reported two fluorescent Zn-based MOFs capable of sensing nitro-containing molecules relevant to detection of explosives. Feng et al. expanded the concept of using MOF structure to tune luminescence by demonstrating that both dynamic structural changes and incorporation of extrinsic dopants within the MOF pores can be used to create intense new emission. Robinson and co-workers reported humidity detection over a very broad concentration range using SAWs coated with Cu-BTC. The MOF film was grown directly on the quartz of 96.5 MHz devices without an intervening SAM, using the layer-by-layer (LBL) growth method developed by Fischer et al.
