文摘

The synthesis of novel metal chelation driven molecular pincers based on crown ether and salen ligand substructures are described. Theirfunctionality was monitored by fluorescence spectroscopy using pyrene groups as fluorescence probes. The pincer was shown to functionreversibly 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.
