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...

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...

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...
