Functional supramolecular systems

In general, our research focuses on the development of bi- and polyfunctional covalently linked and mechanically interlocked frameworks. In this context, we are currently pursuing the synthesis of bis‑1,1´‑binaphthyl-phosphoric acids using different strategies. On one hand, we perform a covalent coupling of two 1,1´-binaphthyl-phosphoric acids. On the other hand, we are investigating the incorporation of two 1,1´‑binaphthyl-phosphoric acids in interlocked catenane structures, thus resulting in bifunctional homo[2]catenanes.


Covalently linked bisphosphoric acids

In this research project, we are interested in the synthesis and application of covalently linked bisphosphoric acids. We have generated a series of rigidly tethered bis-phosphoric acids, realizing that the nature of the tether has a profound influence on their properties. This lead to the identification of one preferred bis-phosphoric acid, which can be used for the chemoselective detection of ferric ions. The presence of Fe3+  can be detected by fluorescence- and CD-spectroscopy, even in the presence of a variety of other metal ions.

Mechanically interlocked bisphosphoric acids

This research project deals with the generation of functional interlocked molecules, such as catenanes and rotaxanes. As a first example, we have reported a novel [2]catenane featuring two chiral 1,1´-binaphthyl-phosphoric acids. This catenane was successfully used as a receptor for chiral diamine-guest and is currently under investigation for a use in catalysis.
