Equivalent to a supercritical fluid is a description of the state of the methane molecule in the interior of the host cavity of a cryptophane molecule. The CH 4 –cryptophane complex (shown on the right) is amazingly stable even at room temperature ( K a = 130 M −1 ), and its half‐life is 6 μs. The findings of this study shed light on the bonding between neutral guest and neutral host molecules.
