主 题：Crown ether complexation crystal structure
摘 要：4 ,5 -Dibromo-o-xylyl-17-crown-5 ether (2BrB17C5) was synthesized,starting from 1,2-dibromo-4,5-bis(bromomethyl)-benzene and tetraethylene glycol,and was characterized by 1H NMR,MS and elemental *** yellow prismatic single crystal obtained from anhydrous ethanol was investigated by X-ray structural *** complexation properties toward alkali metal ions were examined using the solvent extraction method and UV absorption *** crown ether was found to be conformationally deformed and oblate-like and is highly selective for lithium ion.
