“Molecular Recognition with Metal
Complexes and Heterocycles”
Selective recognition of peptides under physiological conditions, specific binding of
a protein surface or guided self-assembly of molecules on surfaces are challenging
tasks in supramolecular chemistry. Synthetic receptors that can achieve such tasks
are interesting as diagnostic tools in medicinal chemistry and molecular biology,
due to their higher stability and simpler functionalization compared to antibodies.
The lecture presents our recent examples of metal complex based luminescent
synthetic receptors, organic peptide mimics and guided self-assembly at interfaces.
Their properties are compared with related systems from literature.
