Cobalt Verdazyl Valence Tautomerization

Research in the Brook Lab focuses on the  study, control and application of the interaction between unpaired electrons. In addition to the role this plays in understanding covalent bonding, these interactions may have applications in magnetic resonance imaging, information storage and molecular computing. Most of our efforts are focused on verdazyl radicals; stable radicals based on a tetrazine ring. One of our more recent results (depicted above) involves a cobalt-verdazyl compound that switches from a high spin cobalt(II) form in the solid state (red) to a low spin cobalt(III) form in solution (green).

Verdazyl Coordination

Metal coordination provides another avenue to modify the verdazyl electronic structure and link free radicals together.
