Novel crown ether and salen metal chelation driven molecular pincers.
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 Zn2+ and also to chelate ditopically with 100 mol % of Zn2+ and 100 mol % Li+ or 200 mol % of Li+ ion.
