Research interests

Neiwert's research focuses on the study of a unique class of inorganic cluster-like compounds known as polyoxometalates (POMs for short). His recent efforts have focused on using POMs as nanoscale building blocks, where they are connected by organic ligands, resulting in inorganic-organic hybrid materials. Multiple spectroscopic techniques are used to characterize POMs and their resulting polymeric materials, including multi-nuclear NMR (1H, 13C, 31P, 29Si, etc), FT-IR, UV-Vis, and single crystal X-ray diffraction.
