Hierarchy is a property associated with multi-level or multi-domain organizations, common in biological systems but also of particular interest in the case of artificial materials. Complex MOF materials with hierarchical structures are expected to demonstrate unusual properties and behaviors. In particular, improving our ability to tune these hierarchical structures on multiple scales will be necessary for the advancement of cooperative catalysis in MOFs, as it requires optimization of both the activity of the catalytic center and selectivity of the porous framework. The strategies Liang developed greatly enrich the scope and applicability of MOF materials and offer opportunities to introduce variates and sequences into three dimensional hierarchical and cooperative systems for heterogeneous catalysis. Hierarchically porous MOFs with tailored pore environment and functionalities were used to heterogeneous catalysis such as the photochemical semisynthesis of an essential antimalarial drug, artemisinin.
