MOLECULAR CLIPS BASED ON THE CROWN ETHERS: PROSPECTIVE RECEPTORS FOR THE Sr2+CATIONS REMOVAL

MOLECULAR CLIPS BASED ON THE CROWN ETHERS: PROSPECTIVE RECEPTORS FOR THE Sr2+CATIONS REMOVAL

Strontium cation complexation with diphenylglycoluril-based molecular clips containing 12-crown-4, 15-crown-5, 18-crown-6 and 21-crown-7 residues was qualitatively studied by FAB mass-spectrometry. It was found that at low concentrations of Sr2+ cations molecular clip with fragments of 15-crown-5 is...
