Estimating the term…
In accordance with the invention, there is provided a method of binding a gas or volatile compound in a cucurbituril, by contacting the gas or volatile compound with the cucurbituril to form a cucurbituril-gas/volatile complex. There is also provided a method of separating a gas or volatile compound from a mixture of compounds wherein the mixture is contacted with a cucurbituril and whereby at least some of the gas or volatile compound is bound to the cucurbituril to form a cucurbituril complex, followed by the release of at least some of the bound gas or volatile compound from that complex. The present invention is thus advantageous in that it allows use of cucurbiturils in binding gases and volatile compounds for storage, safety, delivery or other uses, such as the trapping of an unpleasant or toxic gas or volatile compound.
1) A method of binding a gas or volatile compound in a cucurbituril, said method comprising contacting the gas or volatile compound with the cucurbituril to form a cucurbituril complex of the gas or volatile compound;
8) A method of separating a gas or volatile compound from a mixture of compounds including the gas or volatile compound, said method comprising the steps of:
19) A method of binding dioxane in a cucurbituril, said method comprising contacting dioxane with a cucurbituril selected from the group consisting of unsubstituted cucurbit[6]uril, unsubstituted cucurbit[7]uril and hexamethylcucurbit[3,3]uril, to form a cucurbituril complex of dioxane.
20) A method of binding carbon monoxide in a cucurbituril, said method comprising contacting carbon monoxide with unsubstituted cucurbit[5]uril to form a cucurbituril complex of carbon monoxide.
