Abstract: Embodiments include methods of fabricating a zeolite-like metal-organic framework with an ana-topology (ana-ZMOF) thin film membrane, the methods comprising: (1) modifying a substrate with ana-ZMOF crystal precursors in the presence of polyvinylpyrrolidone; and (2) intergrowing the ana-ZMOF crystal precursors in the presence of polyvinylpyrrolidone to form a continuous defect-free thin film of an ana-ZMOF intergrown on the substrate. Embodiments further include methods of separating chemical species comprising contacting an ana-ZMOF thin film membrane with a fluid composition containing one or more chemical species and separating at least one of the chemical species.

Abstract: An NO2 detection device includes a substrate; a drain formed on the substrate; a source formed on the substrate; a p-type polymer semiconductor layer formed on the substrate, between the drain and the source; and an n-type metal-organic framework layer located over the p-type polymer semiconductor layer. The n-type metal-organic framework layer has apertures having a size larger than a size of the NO2 molecules so that the NO2 molecules pass through the n-type metal-organic framework layer to arrive at the p-type polymer semiconductor layer to increase an electrical current.

Abstract: Embodiments of the present disclosure describe a zeolite-like metal-organic framework composition comprising a metal-organic framework composition with ana topology characterized by the formula [MIII(4, 5-imidazole dicarboxylic acid)2X(solvent)a]n wherein MIII comprises a trivalent cation of a rare earth element, X comprises an alkali metal element or alkaline earth metal element, and solvent comprises a guest molecule occupying pores. Embodiments of the present disclosure describe a method of separating paraffins comprising contacting a zeolite-like metal-organic framework with ana topology with a flow of paraffins, and separating the paraffins by size.
