Pd. Beer et al., A NEUTRAL URANYL DIMERIC COMPLEX AND REMARKABLE EXTRACTION PROPERTIESOF A 1-ACID 3-DIETHYL AMIDE SUBSTITUTED CALIX[4]ARENE LIGAND, Journal of the Chemical Society. Dalton transactions, (17), 1998, pp. 2783-2785
The crystal structure of [(UO2)(2)L-2] (L = 1-acid 3-diethyl amide sub
stituted calix[4]arene) has been determined; the uranyl, lanthanide an
d heavy metal extraction properties of L and of a recyclable polymeric
calix[4]arene based resin material are also described.
