Abstract
In this review the concept of immobilizing electrophilic centers in synthetic cyclic and acyclic (clefts) receptors will be described. Our first attempts using first-row transition metals did not lead to the desired receptors but resulted in hetero-di- and hetero-trinuclear complexes. The properties will be discussed. The use of the uranyl cation (UO2 2+) gave metallocycles and -clefts which are able to complex both neutral polar molecules as anions. The synthesis, X-ray analysis, and complexation behavior will be discussed. Molecular mechanics calculations have been performed in order to rationalize the results.
