THE MILSMANN LAB
Inorganic Chemistry Research at the University of Delaware
We have moved!
As of August 2024, the Milsmann Lab has a new home in the Department of Chemistry & Biochemistry at the University of Delaware.
RESEARCH AREAS
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 synthesis and characterization of isostructural thorium(IV) and uranium(IV) adducts of a pyridine dipyrrolide ligand are reported. The thorium derivatives are photoluminescent, while the uranium complexes are nonemissive.

The eight-coordinate zirconium complex Zr(bppda)2 exhibits photoluminescence through a combination of prompt fluorescence and thermally activated delayed fluorescence (TADF) at room temperature. The lowest energy singlet and triplet excited states contain significant ligand-to-metal charge transfer character involving the d0 metal ion. Femtosecond transient absorption spectroscopy revealed slower intersystem crossing rates compared to related Zr(PDP)2 complexes, which were correlated with subtle changes in the electronic structures of the two compound classes.

Three protonation states of a bulky 2,6-bis(pyrrol-2-yl)pyridine were isolated and structurally characterized. Dimeric and monomeric species were identified depending on solvent polarity and hydrogen bonding capabilities. The photoluminescent properties are highly sensitive to the level of protonation, which attenuates the energies of the HOMO and LUMO.
