New publication on multiswitchable molecular materials

Congratulations to Boskovic Group members Gemma Gransbury, Jett Janetzki and Moya Hay on the publication of their paper “Understanding the Origin of One- or Two-Step Valence Tautomeric Transitions in Bis(dioxolene)-Bridged Dinuclear Cobalt Complexes” in  J. Am. Chem. Soc.

Performed in collaboration with Alyona Starikova from the Southern Federal University in Russia and Matt Shores from Colorado State University, this experimental and theoretical study elucidates the molecular requirements for a complex with two bridged cobalt ions to exhibit distinct redox interconversions at each metal site.

The right choice of metal coordination environment and a redox-active bridging ligand with small, but non-zero, intramolecular electronic communication, affords molecules that can be switched between three distinguishable states.  This discovery has far-reaching future prospects for molecular materials with applications ranging from sensing and display devices to quantum computing, molecular electronics, and molecular spintronics.
