Project Title: The good without the bad: selective chelators for beryllium

From mobile phones and aircraft braking systems, to golf clubs and the James Webb Space Telescope, the element beryllium (Be) is increasingly utilised in consumer, scientific and commercial applications. Unfortunately, beryllium has a poor reputation; it is considered the most toxic non-radioactive element on the planet and the cause of the incurable chronic beryllium disease (CBD). Surprisingly, this reputation has not deterred its use in manufacturing, but it has seriously hindered the exploration of the fundamental chemistry of beryllium. Given that Be usage in consumer and industrial products continues unabated, it is imperative that chemical chelating agents be developed for better detection of Be in the environment, that therapies for individuals exposed to beryllium be developed, and that protocols to remediate Be contamination are established. By building a greater understanding of the fundamental coordination chemistry of Be(2+), this project will develop strong, selective chelating agents for beryllium capture using a modern arsenal of chemical techniques.

Project Title: Synergistic control of anion encapsulation: towards drug delivery systems

Sulfate binds strongly to the 6C ligand, forming a dicopper helicate. No evidence is seen for sulfate binding to the 5C ligand. Structural analysis of the 5C helicates with a number of smaller anions has given a firmer understanding of how these anions bind. Detection of the helicate clusters in solution has given us evidence that the helicates are stable in solution. Discovery of the ability to make anion free derivatives has allowed for the direct investigation of anion binding. Binding studies on the 6C helicates has allowed a quantitative assessment of binding strength of a series of anions in this system. Sulfate was shown to bind most strongly to this system. We have proven the system can act as a reversible pH controlled anion binder which has implications for hydrometallurgic and solvent extraction technologies (New discovery 1). We have shown that the metal coordination core can be expanded in the related oxime system which has implications for storage and electronic communications devices (New discovery 2).
