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.
