Abstract:
Triazole-bearing calixpyrroles (TCPs) were synthesized as artificial anion binding receptors. The additional C-HX hydrogen bonding interaction induced strong binding affinity towards halide ions. Using this strong binding affinity, Cl- was successfully extracted from the aqueous to organic phase.
