## Abstract The Schiff base‐containing pendant monoaza crown ether HL^1^, HL^2^, HL^3^ and HL^4^ have been synthesized by condensation of salicylaldehyde with __N__‐(4‐aminoaryl) monoaza crown ethers, which were prepared conveniently from 4‐nitro‐__N, N__‐di(hydroxyethyl) aniline or 4‐nitrobenzyl c
