dc.description.abstractA convenient synthesis and Cr(VI) extraction properties of a new calix[4]arene-based receptor (5), which has been synthesized from 5,17-diformyl-25,27-dimethoxy-carbonylmethoxycalix[4]arene (4) by treatment with 3-aminomethylpyridine in one step, are described. The receptor 5 contains four pyridinyl groups, two on each rim. Two of them are joined by an amide linkage onto the lower rim, and other two are linked by an imine-type linkage onto the upper rim of the calix[4]arene moiety. Receptor 5 is very soluble in water at low pH (<2.5). Calixarene 5 also represents a good extractant for HCr2O7-. Thus, the partially protonated form of 5 is an effective extractant for transferring HCr2O7- ions from an aqueous into a chloroform layer. Deprotonation of 5 results in a reversal, with HCr2O7- migrating back into the aqueous layer.en_US
