Timothy P. Hanusa

Professor of Chemistry
Associate Director, Interdisciplinary Graduate Program in Materials Science


In the Hanusa group, we have extensively used rational ligand design to control the reactivity of main-group and transition metal organometallic and coordination complexes, investigated steric effects on the reactivity and magnetic/electrochemical properties of metal complexes, and synthesized precursors to materials with desired electronic/optical properties. In particular, we are developing new syntheses for molecular complexes and nanoparticles that use mechanochemical methods, in which the reagents are ground or milled together, rather than being dissolved in a solvent. This can not only provide compounds that are more highly reactive than those formed in solution, but it offers a “greener”, more environmentally conscious route to synthetic nanochemistry than is usually the case.
