Abstrakt: The synthesis of novel metal chelation driven molecular pincers based on crown ether and salen ligand substructures are described. Their functionality was monitored by fluorescence spectroscopy using pyrene groups as fluorescence probes. The pincer was shown to function reversibly with respect to metal chelation with Zn2and also to chelate ditopically with 100 mol % of Zn2and 100 mol % Lior 200 mol % of Liion.
