Methyl‐Substituted α‐Cyclodextrin as Affinity Material for Storage Separation and Detection of Trichlorofluoromethane

摘要

The severely ozone‐depleting trichlorofluoromethane is still appearing in several recycling processes or industrial applications. A simple and selective supramolecular complex formation of per‐methylated α‐cyclodextrin (>1) with the highly volatile trichlorofluoromethane (>2) is reported. This interaction moreover leads to thermally stable crystals. Per‐methylated α‐cyclodextrin is successfully exploited as a reversible and selective adsorption material for liquid and airborne trichlorofluoromethane as well as an affinity material for the chemical sensing and detection of this particular volatile organic component.
