Prof. Robert Luxenhofer (University of Würzburg, University of Helsinki)

Investigation of the underlying drug-polymer interactions responsible for different polymer dependent drug loadings observed by the Luxenhofer group (Luxenhofer et al. JACS 2017). To gain molecular insights, solid-state NMR at different MAS frequencies complemented by GIPAW (CASTEP) calculations are employed.

Assistant Prof. Dr. Irina Delidovich (TU Wien)

Structural characterization of boronic acid functionalized cross-linked polymers for the application in mixture separation. ¹H, ¹³C CP/MAS and ¹¹B NMR are versatile tools to study the binding and release of diols to and from the boronic acid moiety located inside the polymer. Further studies also include tin organic frameworks, which can be used as catalysts, or studies with zeolithe.
