Dynamic Acylhydrazone Metal Ion Complex Libraries: A Mixed–Ligand Approach to Increased Selectivity in Extraction

The dynamic nature of metal–ligand interactions facilitates the formation of metal ion acylhydrazone complex libraries. From these libraries, metal ion complexes with two different types of ligands (1–14; R1≠R2) are shown to have superior extraction properties. Mixed–ligand combinations enhance the selectivity of extraction of ZnII over CdII (see figure).
