Figure 7. (A) Illustration showing the preparation of (4,8)-connected flu and (4,12)-connected ith topologies from a tetrahedral ligand, involving Zr₆ and Zr₉ nodes, respectively; (B) Stepwise process for the rigidification and steric modification of tetrahedral ligands to create NPF-520 with ith topology; (C) Diagram depicting the charge transfer mechanism from Fe^III to Zr-oxo cluster in the Fe^III-decorated Zr₉ node (with Zr in violet, O in red, Fe in orange, and Cl in green); (D) Development of reaction intermediates when water is present versus in an anhydrous environment; (E) Proposed pathway for the photocatalytic oxidation of toluene.
