Electronic Properties of Bisporphyrin Biradical Dications
Autor: David A. Shultz, Kay A. Sandberg, Kevin P. Gwaltney, Hyoyoung Lee
Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 334:459-467
We describe the oxidations of bisporphyrins 1-Zn2 - 6-Zn2 , and present EPR spectra of chemically oxidized species that are consistent with exchange-coupled biradicals.

Semiempirical computational assessment of porphyrins as building blocks for molecule-based magnets: spin-spin coupling in radical-substituted metalloporphyrins
Autor: David A. Shultz, Kay A. Sandberg
Publikováno v: Journal of Physical Organic Chemistry. 12:10-18
Semiempirical PM3-RHF-CI calculations were used to probe structure–exchange coupling relationships in radical-substituted Zn(II) porphyrins. The results support a number of important design elements for creating high-spin molecules from metalloporp

Improved method for estimating the ZFS parameterD for delocalized biradicals
Autor: David A. Shultz, Kay A. Sandberg
Publikováno v: Journal of Physical Organic Chemistry. 11:819-824
An ‘average’ approximation for calculating the zero-field splitting parameter, D, gives reasonable results when used to calculate D values for non-disjoint delocalized organic biradicals. When used to calculate disjoint localized organic biradica

Preparation of meso-tetra(4-galvinolphenyl)porphyrin—A building block for molecular magnetic materials
Autor: David A. Shultz, David A. Knox, Gregory N. Tew, Larry W. Morgan, Kay A. Sandberg
Publikováno v: Tetrahedron Letters. 34:3975-3978
The synthesis and oxidative electrochemistry of a free-radical substituted metalloporphyrin are described. The porphyrin is prepared in four steps in good yield. Oxidation at a platinum electrode shows the molecule undergoes five reversible one-elect
