THE MILSMANN LAB
Inorganic Chemistry Research at West Virginia University
Research in the Milsmann lab combines the areas of physical inorganic chemistry, synthetic inorganic chemistry, and catalysis to find new solutions towards more sustainable and green chemistry. We try to utilize compounds based on earth-abundant elements in (photo)chemical processes that are traditionally dominated by precious metal catalysts. All projects in the group involve the synthesis and manipulation of air-sensitive materials under rigorously inert conditions and take advantage of the large tool box of available physical methods for in-depths analysis and characterization.

The square-planar compound (MesPDPPh)Fe(CPh2) is the first example of an iron carbene complex containing an intermediate-spin iron center. This unique electronic structure gives rise to a paramagnetic ground state with large unquenched orbital angular momentum. The resulting highly anisotropic magnetic properties are established by magnetic susceptibility measurements and applied-field Mössbauer spectroscopy. Computational analysis using the spectroscopy-oriented configuration interaction (SORCI) method provides further insight and reproduces the unusual magnetic behavior of the complex.

A new pyridine dipyrrolide (PDP) ligand variant with 2,6-dichlorophenyl groups shows increased stability towards oxidative degradation and allows the isolation of a high-valent iron imido compound. Short contacts between the chlorine substituents and the iron center result in significant changes to the solid state structures of the new iron PDP complexes.

Understanding the photophysical properties of transition-metal complexes is paramount to advances in photocatalysis, solar energy conversion and light-emitting diodes. Now, long-lived emission via thermally activated delayed fluorescence has been demonstrated from an air- and water-stable zirconium complex featuring excited states with significant ligand-to-metal charge transfer character.
