Lithium Selectivity of Crown Ethers: The Effect of Heteroatoms and Cavity Size

Thermodynamic study of crown ether–lithium/magnesium complexes based on benz-1,4-dioxane and its homologues

“…10,[13][14][15][16] Different cavity sizes, heteroatoms within the ring such as nitrogen or sulfur, substituents, and complex stoichiometries have been investigated. [17][18][19][20] To remove the metal ions from the CE-metal complex, a temperature increase in the system releases the ions from this complex, as shown in the work of Warshawsky and Kahana. 21 In this work, we synthesized different CEs based on benz-1,4-dioxane by increasing the cavity with an increased alkane chain (increasing the hydrophobicity of the CE).…”
