Cucurbituril n [CBn] and cucurbituril n derivative packed ethene or acetylene and release method

The present invention provides a cucurbituril n [CBn] and cucurbituril n derivative wetly-packed ethene or acetylene gas and a release method. First, cucurbituril n [CBn] and a cucurbituril n derivative are relatively poor in water solubility, and can only be dissolved in higher concentration acid to form a small molecule or ion assembly system aqueous solution, the cucurbituril n [CBn] and the cucurbituril n derivative can be dissolved in the aqueous solution by a certain method, and the high concentration can be ensured; second, the ethene or acetylene gas is wetly and drily packed to form a stable solid ethene or acetylene gas inclusion; and third, the ethene or acetylene gas is released by use of an appropriate physical and chemical method.
