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 ; R 1 ≠R 2 ) are shown to have superior extraction properties. Mixed–ligand combinations enhance the selectivity of extraction of Zn II over Cd II (see figure).
