Abstract

Abstract: 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. Abstract : The sweet trap : The ability of per ‐methylated α‐cyclodextrin to selectively form a stable supramolecular complex with the highly volatile trichlorofluoromethane is investigated. The applicability of this supramolecular complex formation is successfully demonstrated as a material for adsorption, separation, and detection of trichlorofluoromethane.
