Synthesis and Characterization of Phenyl-Spaced Nitronyl Nitroxide Semiquione Complexes

Abstract

The study of magnetic materials has become of more interest now that these materials can be utilized in electronics. In the Shultz group we study the fundamentals of high spin biradicals for an understanding of their electronic nature. Past group members have synthesized a new high-spin biradical that combines two different spin containing units: a semiquinone and a nitronyl nitroxide. The work described here is a continuation of the characterization of the phenyl-spaced nitronyl nitroxide semiquinone zinc complex. New EPR studies were performed on the complex to complete the characterization of this high-spin biradical. New synthetic methods of the complex were also explored. Furthermore, a new tris-pyrazolyl borate ancillary ligand was pursued for this semiquinone complex that can be used in future semiquinone complexes.
