In [host–guest chemistry](/source/Host%E2%80%93guest_chemistry), a **carceplex** is a class of chemical structures in the [carcerand](/source/Carcerand) family that are [hinged](/source/Hinge), and can be closed using [reagents](/source/Reagent) that react with the carceplex and trap precursors of [reactive intermediates](/source/Reactive_intermediate),[1] and are unreactive with the trapped precursor or reactive intermediate. This is useful for determining the [spectroscopic](/source/Spectroscopic) and [crystallographic](/source/Crystallographic) properties of reactive intermediates in relative isolation, particularly compounds prone to [dimerization](/source/Dimerization) like [cyclobutadiene](/source/Cyclobutadiene).
