Arbeitsgebiet (Research Interests): Funktionalisierte metallosupramolekulare Tetraeder
The synthesis of supramolecular tetrahedra from C3-symmetric ligands by complexation of metal ions
is a well established method. C3-symmetric ligands, based on a triphenylamine core and three
catechol binding units for complexation of metal ions, have been shown to form stable tetrahedra,
possessing a huge inner cavity, which enables studies towards host-guest chemistry.[1]
Scheme 1: Schematic formation of supramolecula tetrahedra from C3-symmetric ligands.
My work aims for the interconnection of these supramolecular tetrahedra by introducing covalent
bonds between two or more tetrahedra. This can be realized by using the well-known triphenylamine
derived ligands, which are required for a proper formation of the tetrahedra, and which are further
substituted by additional functional groups to allow the cross-linkage of tetrahedra. In 2011, it was
demonstrated that the introduction of an ester moiety to a C3-symmetric ligand will readily provide
functionalized molecular containers.[2] Now the focus is on additional modification allowing the crosslinkage of two or more tetrahedra.
