Fluorescent Halogen Bonding Arylethynyl Scaffolds For Anion Recognition
The synthesis of new molecules designed to bind or sense and report the presence of a particular substrate is an area of chemistry that is attracting attention. There exists a general lack of ligand-specific host molecules, such as specific hosts for toxic ions and small molecules of interest. There also is a dearth of specific hosts that report...

A new method for detection for hydrosulfide anion (HS-) and hydrogen sulfide (H2S)
Hydrogen sulfide (H2S), although generally known for its toxicity and characteristic odor, is now recognized as an important signaling molecule with diverse biological roles. The biological roles of H2S range from roles in angiogenesis to wound healing. In mammals, H2S production is derived primarily from three enzymes: cystathionine-γ-lyase...

A Facile Route to New and Old Cyclophanes from a Pnictogen-activated Self-Assembly Reaction
The well-defined topology and high strain of cyclophanes has found utility in a number of applications including asymmetric catalysis, insulating plastics, and organic electronics. Unfortunately, the field of cyclophane chemistry has been hindered by a lack of high yielding and functional group tolerant preparative methods for their synthesis. University...

Synthesis of Solution Precursors From Aluminum and Gallium Bulk Minerals/Materials
The inventors developed novel methods for producing Keggin-like structures containing 13 metal ions ranging from all Gallium to all Aluminum to mixed metals of metal ions including combinations of Gallium, Aluminum, and Indium. These clusters are preorganized with the desired stoichiometry, which makes them ideal synthetic precursors for thin film...

Tunable Phenylacetylene Scaffolds for Ion Binding
The Phenylacetylenes are a new class of organic compounds that are able to bind negatively charged molecules. The binding of anions is an important problem in chemistry for multiple reasons. For instance, many anions (such as perchlorate, nitrate, and pertechnetate) are environmental contaminants, and recovery of anions from a feed stream may enhance...

Heterometallic Group 13 Keggin-like Nanoclusters
The Johnson research group has developed a high-yielding synthetic strategy for preparing discrete polynuclear inorganic clusters containing thirteen Group 13 metals (Al, Ga, In) in a Keggin-like structure. Seven of the metal ions comprise the interior core, arranged in a flat hexagonal disc and bridged by hydroxo ligands. The remaining six metal...

Tunable Phenylacetylene Scaffolds for Ion Binding updated with additional data
This technology encompasses a series of organic compounds for use in rapid detection of ions and small molecules. These compounds have a previously unknown framework that is modular and pre-organized to bind guests in its cavity. The modular nature of the framework permits easy synthetic variation of the compound structure and several of the...
