Synthesis and Transport of K+ Ions of Mono-Substituted Calix[4]arenes

Abstract

To yield a series of upper rim mono-substituted compounds with potential possibility to polymerize with other monomers, the p-tert-butyl groups were removed from the p-tert-butylcalix[arene, and acrylamido groups were incorporated. These target products were characterized by IR,1H NMR, elemental analysis and ESI-MS. The transport of K+ion was studied. Results indicate the substituting groups with the ability to withdraw electron are benefit to the net transport.
