Effect of calixarene sulfonic acids hydration on their proton transport properties

Abstract

The influence of the morphology of calix(n)arene sulfonic acid hydrates with different number of aromatic rings (n = 4, 6, 8) on their proton transport properties was studied. Simultaneous thermal analysis, IR spectroscopy, X-ray powder diffraction and nuclear magnetic resonance were used for investigating of proton hydrate shell, water content and structure features. It was shown that studied calix(n)arene sulfonic acids hydrates have high proton conductivity up to 10-1 S/cm.
