Hydrocarbons are no longer afraid of water when they are reversibly encapsulated by cucurbituril (see picture). The pumpkin‐shaped molecular container displays a high affinity and selectivity towards neutral molecules in salt‐free aqueous solutions. A supramolecular sensing ensemble, composed of cucurbit[6]uril and an anchored indicator dye, is introduced as a highly sensitive fluorescence‐based online detection tool for gas binding in solution.
