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 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.
