“…Benzo‐9‐crown‐3 CE was synthesized according to a literature procedure. [ 79 ] Catechol (15.6 g, 0.141 mol) and lithium hydroxide (6.77 g, 0.283 mol) were dissolved in 825 mL water and degassed for 1 h. Bis‐2‐chloroethylether (16.6 g, 0.141 mol) was added dropwise to the solution under nitrogen flow and was stirred for 30 min at room temperature. The resulting reaction mixture was refluxed for 86 h at 100 °C.…”

The recovery of lithium from global water resources continues to be challenging due to interfering metal ions with similar solution properties. Hence, a lithium‐selective diblock copolymer system containing crown ethers (CEs) is developed. A polystyrene‐block‐poly(methacrylic acid) diblock copolymer is synthesized first via a one‐pot solution–emulsion reversible addition–fragmentation chain transfer polymerization. A subsequent Steglich esterification yields the CE functionalized polymer. The complexation properties with different alkali metals are first investigated by liquid−liquid extraction (LLE) in dichloromethane (DCM) − water systems using free benzo‐9‐crown (B9C3), benzo‐12‐crown‐4 (B12C4), and benzo‐15‐crown‐5 (B15C5) CEs as reference components, followed by the correspondingly CE‐functionalized polymers. Extraction complexation constants in the aqueous phase are determined and the impact of the complexation constants on the extractability is estimated. The B9C3 CE is especially appealing since it has the smallest cavity size among all CEs. It is too small to complex sodium or potassium ions; however, it forms sandwich complexes with a lithium‐ion resulting in extraordinary complexation constants in polymer systems avoiding other interfering alkali metal ions. On this basis, a new material for the efficient extraction of lithium ion traces in global water resources is established.

This review summarizes recent progress in synthetic methodologies of chelating polymer ligands such as linear, branched, cross‐linked, grafted polymers, polymer films, liquid crystal polymers, dendrimers, star‐shaped and hyperbranched polymers. The features of methods for producing chelating polymer ligands are considered in detail: free‐radical (co)polymerization, living/controlled radical, metathesis, grafted, chemical oxidized, microwave‐assisted and asymmetric polymerization, electropolymerization, cyclopolymerization, polycondensation, post‐polymerization modification, click chemistry methods and “green” synthesis. The main directions of the development of synthetic chemistry of chelating polymeric ligands are analyzed. The bibliography includes works published in the last five years.

In this work, polymeric sorbents based on polyimides with crown ethers for extraction of metal ions from aqueous environment were determined and investigated. The sorbents were made using various monomers (aromatic acid dianhydrides) and crown ethers. Samples of polymeric sorbents showed high values of the extraction extent of metals ions such as cobalt and cesium, and also good temperature resistance.
