Occlusion and confinement of a [Ru(bpy) 3 ]Cl 2 photocatalyst in the cavities of a γ‐cyclodextrin (CD) metal–organic framework (MOF) does not affect the catalyst's activity but prevents its photodegradation. Additionally, the OH − ions and/or ROH groups present inside the CD‐MOF act as electron donors and complete the catalytic cycle. The occlusion approach is a technically straightforward alternative to the covalent modification of MOF scaffolds with catalytic units.
