The Wiegand research group develops and applies Nuclear Magnetic Resonance (NMR) spectroscopy techniques to probe weak chemical interactions in solid-state molecular recognition processes. Molecular recognition plays a fundamental role in many disciplines of life sciences and is essential in biology and chemistry. It is driven by the cooperative interplay of noncovalent interactions (NCIs), such as hydrogen bonds, dispersion or cation-π interactions. Solid-state NMR allows us to shed light on the atomic-level details of molecular recognition in rather diverse fields of biological and chemical sciences. We currently focus in collaboration with our partners on four selected research topics, namely mechanochemically-induced organic reactions, multifunctional heterogeneous catalysts, cellular organization by phase separation and protein-nucleotide binding in ATPases. Our research themes require the continuous further development of the solid-state NMR methodology in concert with computational modelling, particularly focussing on proton-detected solid-state NMR at magic-angle spinning (MAS) frequencies of 100 kHz or even higher as well as paramagnetic NMR spectroscopy in solids.
Probing NCIs by solid-state NMR. The group develops a set of dedicated proton-detected solid-state NMR experiments enabling the detection and quantification of NCIs.[1] Until recently, however, proton-detected solid-state NMR spectra often used to be uninformative due to lack of resolution. However, with the significant line-narrowing achieved with the advent of fast MAS techniques (MAS frequencies larger than 100 kHz) the protons engaged in various types of NCIs can be resolved and identified. We interpret our experimental results in feedback with quantum-chemical calculations on how NMR observables are influenced by NCIs. Current examples comprise lanthanide-π containers that trap small guest molecules.[2]
Organic mechanochemistry. Solid-state molecular recognition in mechanochemically-induced organic reactions is a central research topic in the group. Spectroscopic techniques are crucial for shedding light on the mechanisms of such reactions and solid-state NMR offers a variety of opportunities in this research field (for a recent review see [3]). We currently focus on the mechanochemical racemic-phase formation of chiral organic molecules, as well as amino acids.[4] The technique of resonant-acoustic mixing as an alternative tool is further explored in our laboratory.[5] Mechanistically, we explore solid-state NMR to disentangle the various effects affecting mechanochemical reactions.[6] A current application aims at combining the concepts of mechanochemistry and Frustrated Lewis Pair chemistry. Novel insight into mechanochemical reactions is often combined with using the target compounds for NMR methodological work (for recent examples see [7-8]).
Multifunctional catalysts. We investigate among others supported ionic-liquid phases involving metal(phosphide) nanoparticles. A particular focus lies on probing the conformation of ionic liquids (IL) on such surfaces and to explore the roles of ordering phenomena as well as IL dynamics in catalytic processes. We are establishing homonuclear distance measurements for catalytic materials in the fast MAS regime, particularly for those materials possessing a large chemical-shift anisotropy impairing with accurate distance measurements. In addition, we apply proton-detected solid-state NMR experiments at MAS frequencies >100 kHz using adiabatic pulse schemes to characterize paramagnetic lanthanide complexes, which for instance allows us to probe magnetic susceptibility tensors in the solid state.
Cellular organization by phase separation. A central molecular-recognition event the group is focussing on is liquid-liquid phase separation and subsequent liquid-to-solid phase transition of proteins linked with neurodegenerative diseases. Real-time solid-state NMR allowed us to monitor liquid-droplet maturation of the Fused in Sarcoma protein and to follow amyloid fibril formation.[9] Small peptide derivatives designed based on the “sticker-and-spacer” concept have been studied as model systems.[10]
ATP-hydrolysis in ATPases. The group explores solid-state NMR spectroscopy to monitor ATP-hydrolysis in various ATPases, in many cases by real-time NMR spectroscopy focussing on the detection of the nucleotide. A particular focus lies on studying protein-nucleotide interactions, e.g. by probing hydrogen bonds. Our current protein systems range from proteins involved in DNA replication[11-12] to ATPases of relevance in the biogenesis of iron-sulphur clusters.
