Five new aza-crown ethers have been prepared by the condensation of 2,6-bis[(2-formylphenyl)oxymethyl] pyridine with different diamino compounds in hot methanol, the bis-Schiff bases without isolation were reduced with NaBH₄ to afford the corresponding aza-crown ethers. The liquid membrane transport of alkali cations using the five new macrocycles as the ion-carriers was also studied.
- Aza-crown ether,
- macrocycle,
- receptor,
- liquid membrane transport,
- picrate.
