We disclose here that porous molecular crystals of compound 1 (Figure 1) can adsorb fluorinated anesthetics to the tune of up to 63 percent by weight. Synthesis of compound 1 and its applications in the adsorption of other analytes (not related to the medical field) has been previously reported by us in a publication (ref. 1) and a provisional patent (ref. 2). This application may be important in the general field of anesthesia as it relates both to the delivery of anesthetic gases to the patient and their sequestration following the procedure. Since these gases are rather expensive, their recycling is an economically viable and potentially profitable option.
