“…Metal–organic polyhedra (MOPs), also known as metal–organic cages, are a class of discrete molecular assemblies fabricated from organic ligands and metal ions under supramolecular interaction forces. With well-defined internal cavities, good dispersibility, and intrinsic topological structural versatility, MOPs have shown intriguing potential for applications in gas storage and separation, − catalysis, , sensing, and magnetism . However, as compared to the porous network materials, including metal–organic frameworks, covalent-organic frameworks, and zeolites, MOPs are relatively unexplored, especially stimuli-responsive MOPs (sr-MOPs) .…”

The fabrication of molecular crystalline materials with fast, multistimuli-responsive behavior and the construction of the corresponding structure−activity relationship are of extraordinary significance for the development of smart materials. In this context, three multistimuli-responsive functional metal−organic polyhedrawere successfully prepared and characterized. All of the compounds exhibit rapid and reversible photochromic and electrochromic dualresponsive behaviors. Furthermore, benefiting from the well-defined crystal structure and different responsive behaviors, the photoinduced electron transfer (PIET) process and structure−activity relationship were explored. In addition, considering the excellent photochromic performance, function filter paper and smart organic glass were successfully prepared and used for ink-free printing and UV light detection.

The extensive use of pesticides to ensure global food production presents significant threats to both human health and the environment. In this study, the photochemical, redox, and acid‐base properties of Zr‐metal‐organic polyhedra (Zr‐MOP) and polyoxometalates (POM) are utilized to fabricate functional hybrid salts, denoted as [Zr‐MOP][POM], designed for pesticide detoxification. Upon light irradiation, [Zr‐MOP][POM] salts generate a charge‐separated state with oxidizing properties. This activated state selectively photooxidizes highly toxic and persistent fenamiphos into fenamiphos sulfoxide and subsequently hydrolytically breaks down it into non‐toxic 3‐methyl‐4‐(methylsulfinyl)phenol and phosphate components. The hydrolytic degradation of fenamiphos is facilitated by the reduced basicity of the 3‐methyl‐4‐(methylsulfinyl)phenolate residue (ΔpKb = ‐2.4) in the photooxidized form of the pesticide molecule. Furthermore, the hybrid salts demonstrate efficacy in the breakdown of multicomponent pesticide mixtures such as fenamiphos and methylparaoxon.
