| 摘 要： | Three novel benzocrown ether derivatives have been synthesized and their cation binding behavior with uniand bi-valent metal ions was evaluated by the solvent extraction of aqueous metal picrates. The obtained results indicate that the size-fit of crown ether and metal cation, and electron effect of the side arm attached to benzocrown ethers affect their cation binding ability and selectivity.

| Abstract: | Three novel benzocrown ether derivatives have been synthesized and their cation binding behavior with uni- and bi-valent metal ions was evaluated by the solvent extraction of aqueous metal picrates. The obtained results in-dicate that the size-fit of crown ether and metal cation, and electron effect of the side arm attached to benzocrown ethers affect their cation binding ability and selectivity. |
