Strapped calix[4]pyrrole as a lithium salts selective receptor through separated ion-pair binding

A triazole-bearing strapped calix[4]pyrrole ( 1 ) was synthesized as a lithium salt selective ion pair receptor. 1 H NMR spectral studies and X-ray crystallography showed that the capture of LiCl by 1 occurs via separated ion pair binding. Furthermore, lithium salts extracted by 1 could be solidifie...

Summary:A triazole-bearing strapped calix[4]pyrrole ( 1 ) was synthesized as a lithium salt selective ion pair receptor. 1 H NMR spectral studies and X-ray crystallography showed that the capture of LiCl by 1 occurs via separated ion pair binding. Furthermore, lithium salts extracted by 1 could be solidified in the form of Li 2 CO 3 through CO 2 or K 2 CO 3 treatment. A triazole-bearing strapped calix[4]pyrrole ( 1 ) was synthesized as a lithium salt selective ion pair receptor.
