Our work combines crystallography, chemical synthesis, theoretical chemistry and spectroscopy in a comprehensive approach to chemical research. It includes the development of new methods for the study of solids by X-ray diffraction and spectroscopy. Using synchrotron radiation and excitation by laser-light at low temperature we determine the geometry of molecular species that exist for only microseconds or less. We also study chemical reactions in complex solids and examine how the molecule changes and the kinetics of change as the reaction proceeds.
We use the methods of crystal engineering to synthesize new supramolecular solids. They are used to study the properties of molecules embedded as guest in the cavities of molecular frameworks. As in solutions this allows molecular dilution, but with the distinction that a periodic array is maintained.
As X-rays are scattered by the electrons, X-ray diffraction can be used to map the electron distribution in solids, thus shedding light on the chemical bonding in molecules. Recently, we have focused attention on the derivation of the electrostatic potential and other electrostatic properties, such as dipole and quadrupole moments. The electrostatic properties are of importance for the understanding of chemical reactivity, the lattice energy of crystals, the folding of biological macromolecules, and the interactions between enzymes and substrates.
