organic frameworks that include catalytic components incorporated throughout the framework. These covalent organic frameworks have unique structural and physical properties, which lend these frameworks to be versatile and useful in a number of different applications and uses and chemical reactions. In one, the covalent organic frameworks include a plurality of fused aromatic groups or polyaromatic groups and ligands, where catalytic components such as transition metal catalysts are coordinated by the ligand to the frameworks.

Disclosed herein is a decontaminant aqueous solution for decontaminating diisocyanate drum, including 20-97 wt % of at least one alcohol or derivative thereof, based on the total weight of decontaminant aqueous solution, and an alkaline source in an amount effective to provide the solution a pH of at least 8. Further disclosed herein is a method for decontaminating diisocyanate residues in an emptied drum with the decontaminant aqueous solution.

Materials for decontamination of compounds having a phosphorous-sulfur bond or a phosphorous-oxygen bond. A porous polymer, such as poly(dicyclopentadiene), contains particles of zirconium hydroxide. The polymer optionally has hydroperoxide groups.

Enzyme-immobilizing MOFs and methods for their use in enzymatically catalyzed reactions are provided. The MOFs are channel-type MOFs that present a hierarchical pore structure comprising a first set of large channels sized for enzyme immobilization and a second set of smaller channels running alongside of the large channels that remain enzyme-free and allow for reactant delivery to the enzymes and product expulsion from the larger channels.

A composite material is provided comprising a porous polymeric matrix having metal-organic framework (MOF) domains dispersed within the porous polymeric matrix, each of said MOF domains in fluid communication with the external environment through the pores in the porous polymeric matrix. A process of using the composite material to chemically modify or detoxify a chemical warfare agent or a toxic industrial chemical is also provided. The chemical warfare agent or the toxic industrial chemical is brought into contact with a MOF domain within the porous polymeric matrix so that the MOFs adsorb and chemically modify the chemical warfare agent or the toxic industrial chemical. A process for producing such a composite material is also disclosed.

Disclosed is a method of decontamination by exposing a zirconium oxy(hydroxide) aerogel to a liquid, vapor, or gaseous sample suspected of containing a phosphonate compound. The aerogel may be doped with Fe.sup.3+ ions, Ce.sup.3+ ions, or SO.sub.4.sup.2− ions. The aerogel may be made by: providing a solution of ZrCl.sub.4; FeCl.sub.3, CeCl.sub.3, or Zr(SO.sub.4).sub.2; and a solvent; adding a cyclic ether to the solution to form a gel; infiltrating the gel with liquid carbon dioxide; applying a temperature and pressure to form supercritical fluid carbon dioxide; and removing the carbon dioxide for form an aerogel.

Textile fibers at least partially coated with a coating that includes particles of metal-organic frameworks dispersed in a polymeric base are provided. Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.

The titanium (IV) and iron (III) MOF solid MUV-17 (TiFe.sub.2), has general formula (1): [Ti.sup.IVFe.sup.III.sub.2(O)(L).sub.2(X).sub.3]S, where X is each equal or different selected from: O.sup.2−, OH.sup.−, H.sub.2O, F.sup.−, Cl.sup.−, Br.sup.−, I.sup.−, NO.sub.3.sup.−, ClO.sub.4.sup.−, BF.sub.4.sup.−, SCN.sup.−, OH.sup.−, CH.sub.3COO.sup.−, C.sub.5H.sub.7O.sub.2.sup.−, SO.sub.4.sup.2− and CO.sub.3.sup.2−, L is a tricarboxylic ligand and S is at least one molecule of a polar solvent selected from the group consisting of N,N′-dimethylformamide,N,N′-diethylformamide,N,N′-dimethylacetamide, N-methyl-2-pyrrolidone, methanol, ethanol, isopropanol, n-propanol, water and mixtures thereof. The titanium (IV) and iron (III) MOF solid has long-term catalytic activity for the degradation of toxic compounds. The method for obtaining them comprises dissolving the components under anaerobic conditions. The invention also relates to the use of the titanium (IV) and iron (III) MOF solid as an additive with detoxifying properties of toxic compounds.

The present invention relates to a method for modifying a textile yarn or fabric by immobilising a cyclodextrin derivative on said yarn or fabric, said process comprising a step (a) of contacting said textile yarn or fabric with said cyclodextrin derivative and with a bridging agent such as 1,2,3,4-butanetetracarboxylic acid, optionally in the presence of a catalyst such as cyanamide,

to obtain a textile yarn or fabric on which the cyclodextrin derivative of formula (I) is immobilised.

Provided are MOF-fabric composites having a crystalline MOF adhered directly to fibers of the fabric and methods of making MOF-fabric composites. A solution is adsorbed onto a fabric. The solution can include a metal salt, a linker, and a solvent. The solution is adsorbed onto the fabric and the fabric suspended over a heated vapor. The vapor releases onto the fabric, causing the metal salt, the linker, and the solvent to diffuse out of the polymer fibers. The linker links metal from the metal salts to form crystals attached to the fabric, and the vapor aids crystallization.
