Research Interests
We are working to find or invent compounds that will signal the presence of metal ions by showing enhanced fluorescence or by giving altered signals in their 13C or 1H NMR spectra. Compounds with this capability, called chemosensors, could be used for the measurement of the concentrations of metal ions in solutions of analytical, biological, or medical interest. We have focused on a class of macrocyclic compounds called crown ethers which have the ability to complex and hold metal ions and ammonium ions.
