Our group uses fluorescence, the light emitted by electronically excited molecules, to study the properties of the molecules. We are particularly interested in supramolecular host-guest inclusion complexes, in which a small fluorescent "guest" molecule becomes trapped inside the cavity of a larger, cage-like "host" molecule. Such systems have numerous applications, including as molecular sensors, and in trace analysis techniques, such as for pesticides in natural waters.
