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. T...

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...

Chemiluminescent Probe for H2S Detection
Hydrogen sulfide is an important biological signalling molecule and an important environmental detection target. Biological H2S exhibits significant effects in both the cardiovascular and neuronal systems and is produced endogenously from cystathionine-β-synthase (CBS), cystathionine-gamma-lyase (CSE), and 3-mercaptopyruvate sulfur transferase...

Phenyl SAMMS 2
The need to develop inexpensive and efficient filtration media is a high priority for researchers, and in turn offers a challenge for finding new, functional, designer materials that have high uptake capacities and selectivity for environmental contaminants. Phenyl SAMMS is one such high uptake, selective binding substrate. Self-Assembled Monol...

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 e...

Liquid CO2 Visualization Apparatus
The apparatus described here is a teaching tool for instructors to illustrate to students the effect that pressure, temperature and volume have on states of matter (i.e. solid, liquid, gas). Carbon Dioxide is a gas at room temperature and pressure, although most everyone is familiar with solid CO2 --dry ice--which has a temperature of -109.3...

Polymer-Supported Proton Sponge Reagent
Prof. David Tyler’s research group has developed a polymer-supported proton sponge reagent with a visual indicator of its potency. The reagent is colored a deep purple when deprotonated, and this color fades to a light tan as the basic sites are protonated.  Benefits: Easily synthesized in two steps Strong base ...
