The invention concerns methods of removing undesirable molecules from the blood or physiologic fluid; said method comprising contacting said blood or physiologic fluid with a sorbent, said sorbent comprising a plurality of solid forms and comprising a cross-linked polymeric material having a plurality of ligands attached to the surface of said cross-linked polymeric material, comprising (i) zwitterionic moieties, (ii) oligo(ethylene glycol) moieties or (iii) mixtures thereof; said contacting comprising said sorbent sorbing a plurality of said undesirable molecules when said sorbent is administered within a patient's body.

Disclosed are air-stable small-molecule adsorbents trimeric [Cu—Br].sub.3 and [Cu—H].sub.3 that undergo a reversible solid-state molecular rearrangements to [Cu—Br.(alkene)].sub.2 and [Cu—H.(alkene)].sub.2 dimers. The reversible solid-state rearrangement allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake.

An adsorbent includes a porous substrate and a carboxylic acid dimer loaded onto the porous substrate. The carboxylic acid dimer is loaded on the surface or in the plurality of holes of the porous substrate. The average pore size of the porous substrate is not smaller than 2 nm. The carboxylic acid dimer is loaded onto the porous substrate by at least one of the following manners: a) the carboxylic acid dimer is loaded onto the porous substrate through a Si—OH bond; b) the carboxylic acid dimer is loaded onto the porous substrate through the exchange between a carboxyl group and chlorine; c) the carboxylic acid dimer is loaded onto the porous substrate through the exchange between a carboxyl group and a hydroxyl group; and d) the carboxylic acid dimer is loaded onto the porous substrate through the coordination of a carboxyl group and aluminum or silicon.

The present disclosure provides for alkyl-aryl amine-rich small molecules that are prepared by nucleophilic substitution from tri- and hexa-bromine-substituted aromatic cores with various aliphatic diamines. The resulting products can be subsequently subjected by solution impregnation into solid mesoporous supports. Various types of alkyl-aryl amine-rich small molecules can fill the support's pores up to ˜90% and displayed good thermal stability

The present invention is directed to a ligated metal-organic framework (MOF) for use in removing both anionic and cationic species from a liquid or liquid stream. The present invention also provides methods for placing the MOF on a substrate to form a MOF-containing product that can be used in the removal of certain species from a given fluid. The MOF may be a Zr-based MOF, such as NU-1000, for removal of certain anions, such as oxy-anions, or having an attached thiosulfonyl-thiol (—SO.sub.2—S—R.sub.2—SH, where R.sub.2 is an alkyl group) ligand for complexation with certain cationic species in addition to the anions. The substrate may be any substrate to which a given MOF may be attached, including inert polypropylene polymer resin beads, a macroscopic fabric such as a mesh material or mesh filter, and a molecular fabric.

The invention relates to strong hydrogen-bond acidic sorbents. The sorbents may be provided in a form that limits or eliminates intramolecular bonding of the hydrogen-bond acidic site between neighboring sorbent molecules, for example, by providing steric groups adjacent to the hydrogen-bond acidic site. The hydrogen bond site may be a phenolic structure based on a bisphenol architecture. The sorbents of the invention may be used in methods for trapping or detecting hazardous chemicals or explosives.

Chromatography resins having mixed mode ligands and methods of using such resins are provided.

The present disclosure provides a porous polymeric membrane that is coated with a cross-linked polymerized monomer. The coating on the porous polymeric membrane has a charge when it is immersed in an organic liquid. The coated porous polymeric membrane, a filter utilizing the membrane, and a method for treating an organic liquid used for photoresist with the coated porous polymeric membrane to remove metal contaminants from the organic liquid are disclosed.
