One-dimensional channels constructed from per-hydroxylated pillar[6]arene molecules for gas and vapour adsorption.

ABSTRACT

Per-hydroxylated pillar[6]arene molecules formed highly ordered one-dimensional channels with a diameter of 6.7 Å. The channels can capture various gases, such as CO2, N2 and n-butane, and vapours of saturated hydrocarbons such as n-hexane and cyclohexane.
