A new type of water-soluble crown ether (3?-sulfobenzo-12-crown-4 (SB 12C4), 3?-sulfobenzo-15-crown-5 (SB 15C5), 3?-sulfobenzo-18-crown-6 (SB18C6), di(3?-sulfo)dibenzo-18-crown-6 (DSDB18C6), di(3?-sulfo)dibenzo-21-crown-7 (DSDB21C7), and di(3?-sulfo)dibenzo-24-crown-8 (DSDB24C8)) has been prepared. The complex formation constants (beta) of lanthanide ions with sulfonated crown ethers in aqueous solution were determined via the solvent-extraction method. The stability of the resulting complexes increases with the number of sulfonic acid groups, 18C6
