Crown calix[4]arenes, method of preparation and use for selective extraction of caesium

PCT No. PCT/FR98/00401 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Mar. 2, 1998 PCT Pub. No. WO98/39321 PCT Pub. Date Sep. 11, 1998The invention relates to new calixarenes of formula: in which R1 represents a crown ether chain that includes at least two aryl or cycloalkyl rings, R2 is a hydroxyl or alkoxy group, or the two R2 groups together form a crown ether chain such as R1, and R3 represents a hydrogen atom or an alkyl group. The calixarenes are used to selectively extract caesium from aqueous solutions that notably have high concentrations of sodium.

A new calix[4]arene-bis(crown ether) derivative displaying an improved caesium over sodium selectivity: Molecular dynamics and experimental investigation of alkali-metal ion complexation

In the light of computational studies suggesting enhanced cation-binding abilities for various benzo derivatives of calix[4]arene-bis-crown-6 macrocycles, the synthesis and properties of one of these ligands, BC6B2, have been investigated. In this compound, di(1,2-phenylene)-annelated glycolic chains link the 1,3- and 2,4-phenyl rings of the calixarene, thereby forcing it into the 1,3-alternate conformation. The detailed structures of BC6B2·CH3NO2 1 and Cs2(NO3)2BC6B2·CHCl 3·H2O 2 have been established by X-ray crystallography. Studies of coordination and solvent extraction of the alkali-metal ions have been used to compare this ligand with a number of related systems known previously.
