Exploring Magnetic Bistability of Molecules for Rational Design of Spin-Transition and Clock-Transition Complexes

Michael Shatruk

Department of Chemistry & Biochemistry
Florida State University

Chemists’ unique ability to produce “designer” magnetic molecules has come to light recently as relevant to the rapidly emerging fields of molecular spintronics and quantum science. In this talk, I will highlight our work on complexes of 3d and 4f metal ions that exhibit, respectively, abrupt spin transitions and quantum clock transitions in the solid state. After discussing some fundamental structure-property relationships in spin-crossover (SCO) complexes,1 I will highlight our work on the design and synthesis of volatile and exfoliable SCO molecular materials2,3 and investigation of their heterostructures with 2D inorganic materials. In the second part of my talk, I will discuss the design and investigation of lanthanide complexes that exhibit clock transitions, of interest to the development of molecular spin qubits.4
