Research: Our Expertise

 

Mass Spectrometry and Gas-Phase Chemistry of
Non-Covalent Complexes

Analytical characterization, structural studies, comparison of reactivity in the condensed and the gas phase for example of hydrogen-bonded capsules, metallosupramolecular helicates, polygons, and polyhedra, or intertwined molecules such as rotaxanes, catenanes and knots

 

Mass Spectrometric Characterization of Dendrimers

Purity, dispersity, and defect analysis, fragmentation mechanisms, differentiation of structural isomers, host-guest chemistry of dendrons and dendrimers including POPAM, Fréchet-type and persulfonylated dendrimers as well as dendritic self-assembled metallosupramolecular squares.

 

Synthesis and Characterization of Interlocked Molecules

Templated synthesis and functionalization of interlocked molecules, deslipping kinetics of rotaxanes for the evaluation of the steric size complementarity of the wheel's cavity and the stopper size, controlled molecular movements in molecular devices

 

Self-Assembly of Metallosupramolecular Polygons and Polyhedra

Formation and ligand exchange mechanisms, thermodynamic and kinetic properties, cages with converging functional groups, dynamic combinatorial libraries

 

Anion Recognition

Gas-phase studies on anion recognition, C-H/anion interactions, anion/pi interactions
