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.
Below you will find a selection of our team’s most recently published papers. Click on the title or picture for a link to the article. A complete list of the group's research articles can be found here.
ORGANOMETALLIC INTERMEDIATES IN THE SYNTHESIS OF PHOTOLUMINESCENT ZIRCONIUM AND HAFNIUM COMPLEXES WITH PYRIDINE DIPYRROLIDE LIGANDS

The synthesis of air- and moisture-stable Zr(PDP)2 photosensitizers proceeds via a cyclometalated intermediate. Extending our previously reported synthesis to hafnium allowed the first report of photoluminescent Hf(PDP)2 complexes.
LONG-LIVED PHOTOLUMINESCENCE FROM AN EIGHT-COORDINATE ZIRCONIUM(IV) COMPLEX WITH FOUR 2-(2′-PYRIDYL)PYRROLIDE LIGANDS

The photoluminescent eight-coordinate zirconium complex Zr(HPMPH)4 shows dual emission via fluorescence and phosphorescence with an overall quantum efficiency of 4% at room temperature in solution. The phosphorescence lifetime is dependent on concentration, indicating excimer formation at higher concentrations, and reaches almost 800 μs at high dilution.
CARBENE TRANSFER FROM A PYRIDINE DIPYRROLIDE IRON–CARBENE COMPLEX: REVERSIBLE MIGRATION OF A DIPHENYLCARBENE LIGAND INTO AN IRON–NITROGEN BOND

Addition of isocyanides to a square-planar iron-carbene complex results in facile carbene insertion into an Fe-N bond of the supporting pyridine dipyrrolide pincer ligand. This reaction is fully reversible and allows carbene transfer to generate ketenimines at elevated temperatures.
