Crown Ether Schiff bases and their Complexes: Recent Advances (A Review )

Abstract

In latterly years, an interest in the synthesis of crown ether Schiff bases and their Complexes has been increased, due to the significance and broadly the uses of these compounds in various fields. In the present review paper outline extensive recent advances literature survey on the crown ether including azomethine gathering and their complexes with the tough and easy granter atoms, has been reconsidered. Assertiveness has been done on element complexation with crown ether holding Schiff bases to enable the researchers to procure valuable information of the chelating activity of crown ether containing azomethine gathering and their enforcement.

Synthesis, characterization, and antimicrobial activities of novel double-armed benzo-15-crown-5 and their sodium and potassium complexes

“…Numerous types of macrocyclic ligands and their complexes have been synthesized, including crown ethers. [1][2][3][4][5][6] Structurally, crown ethers are cyclic structures having a cavity that allows them to form stable complexes with metal ions. [7][8][9][10][11] In particular, bis-crown ethers have superior selectivity for metal cations.…”

“…There are also examples of substituted crown ethers having different selectivity centers. 6,[13][14][15] The crown ether center can generate stable complexes with alkali metal and alkaline earth metal cations, while the substituted side center can form transition metal complexes. 12,[16][17][18][19][20][21][22][23] Their complexing properties make crown ethers especially interesting and useful compounds in biological research and in chemistry.…”
