Crown Ethers and Cryptands for Advanced Applications

Crown ethers and cryptands, complexing agents able to selectively bind metal cations, are vital for diverse synthesis and analytical applications.

Synthesis of novel ion-imprinted polymeric nanoparticles based on dibenzo-21-crown-7 for the selective pre-concentration and recognition of rubidium ions.

Beshare Hashemi et al.

Journal of separation science, 38(24), 4248-4254 (2015-10-16)

In this work, we report the first application of ion-imprinted technology via precipitation polymerization for simple and practical determination of rubidium ions. The rubidium-ion-imprinted polymer nanoparticles were prepared using dibenzo-21-crown-7 as a selective ligand, methacrylic acid as functional monomer, ethylene
