Water-sensitive gas fluorotrimethylsilane could be trapped and stabilized by Cucurbit[7]uril (CB[7]) to the expense of the hydrolyzed trimethylsilanol in aqueous medium and in the solid state. To the best of our knowledge, this represents the first case of reactive gas encapsulation into CB[n]s. This mechanism is applied to the design of a simple fluoride-controlled molecular switch. We then show that CB[n]s can also stabilize silver nanoparticles in aqueous medium, and we discuss the impact of the CB[n] ring size.
