A molecule of luminol bound as guest inside a Co coordination cage host undergoes oxidation by HO to generate chemiluminescence by a process in which the Co(II) ions in the cage superstructure activate the HO: accordingly the cage not only co-locates the reactants but also acts as a redox partner in the catalysis. The luminescence from oxidation of the cavity-bound luminol can transfer its excitation energy to surface-bound fluorescein molecules in an unusual example of Chemiluminescence Resonance Energy Transfer (CRET).
笼状主体 Co 配位化合物内的客体分子 luminol 通过 HO 氧化，在笼状超结构中的 Co(II) 离子激活 HO 的过程中产生化学发光：因此，该笼不仅共定位反应物，而且在催化中充当氧化还原伴侣。空腔结合的 luminol 氧化产生的发光可以将其激发能量转移到表面结合的荧光素分子上，这是化学发光共振能量转移（CRET）的一个不寻常例子。
