A shape-dependent hydrophobic effect for tetrazoles

An adaptive tetrazole-derived host provides insight into tetrazolate-biomolecule interactions, and is the first member of a new family of receptors that function in pure water. The Royal Society of Chemistry.

COMPOUNDS AND METHODS FOR CHELATING METALS IN AQUEOUS SOLUTIONS

The present invention relates to a new class of organic compounds and their use, for example, to sequester metal ions, including actinides (such as uranium and plutonium), precious metals (such as gold, silver and platinum) and all other metals (such as transition metals), from aqueous solutions, such as bodies of water (including but not limited to ocean water, seawater, river water) and all other aqueous solutions. Specifically, the present invention relates to a new class of polydentate organic chelating agents and methods for their use to recover metals from aqueous solutions, such as uranium from seawater.

Selective recognition and extraction of the uranyl ion

A tripodal receptor capable of extracting uranyl ion from aqueous solutions has been developed. At a uranyl concentration of 400 ppm, the developed ligand extracts ～59% of the uranyl ion into the organic phase. The new receptor features three carboxylates

Synthesis and binding studies of bowl-shaped hosts for quaternary ammoniums

Two bowl-shaped hosts for quaternary ammonium salts were synthesized and their binding properties, along with the anion effect, were systematically examined and compared in CDCl3.

"Flexiball" toolkit: A modular approach to self-assembling capsules

We report the synthesis and characterization of new, self-assembling molecular capsules. The modular strategy makes use of glycoluril building blocks available in multigram amounts combined with aromatic spacer elements. The lengthy syntheses encountered with earlier generations of capsules are avoided, and several capsules of nanometer dimensions are now accessible. Single bond attachments between spacers and glycoluril modules result in monomers as dimeric capsules that are less rigid than their earlier counterparts. The host-guest properties of the homo- and heterodimeric capsules were studied using a combination of NMR and ESI-mass spectrometry. They show a less pronounced selectivity for guests of different sizes, and their increased flexibility prevents self-assembly when no rigidifying elements are present on the central spacer unit. Some of the new capsules bear inwardly directed, secondary amide N-H protons. These can be further functionalized, as shown by their methylation to give tertiary analogues. The structures hold broader implications for the placement of functional groups on concave molecular surfaces.
