Abstract Controlling the generation and release of singlet oxygen ( 1 O 2 ) with high oxidation activity long lifetime properties holds significant potential for efficient permanent organic pollutants, tumor eradication, targeted molecular oxidation. However, conditions controlled remain unclear. Hence, novel anthracene‐ligands based Zr‐MOFs which use acetic acid (HAc) are constructed to optimize surface defects specific area exhibit ultrafast saturation adsorption capacity (362.60 mg g −1 in 60 s) deep photodegradation performance toward bisphenol A (BPA) water (50 ppm 20 min) via Zr‐DPA MOF‐1HAc. Mechanistic studies have shown that MOFs capable generating concentrations , while anthracene ligands can rapidly store form endoperoxides (EPOs), be released under external light, heat, or chemical triggering conditions. Thus, concentration is always involved reaction throughout whole process ultimately achieves complete mineralization target phenolic pollutant molecules. This innovative strategy has important implications generating, storing controlling field environmental engineering synthesis.

Abstract Defect‐engineering‐involved metal‐organic frameworks (MOFs) have been highly valued in many fields due to the enhanced porosity and abundant active sites, but how systematic modulation on deficiency influencing fluorescent sensing performance is still its infancy. Here, defect‐engineering of MOF‐525 used modulate exposure zirconium (Zr) clusters sieving capability inner channels, enabling precise phosphoryl fluoride nerve agents with specific chemical activity molecular dimensions. Controllable defects transformed localized emission porphyrin into ligand‐metal charge transferring (LMCT) gradual loss ligand molecules, which interrupted upon coordination agents, triggering a red turn‐on fluorescence. Thus, defective 60% effectively discriminates (e.g., sarin, soman) from similar substances tabun, venomous agent X) synergistic effect dimension. It exhibits sensitive (0.96 n m /3.8 ppb), rapid (<1 s) response toward target robust environmental interference acidic, humid common substances. This work enhances understanding MOFs correpsonding luminescent behavior, paving new avenue for strategy trace real vapor.

Defect engineering has developed over the last decade to become an inimitable tool with which shape Metal-Organic Framework (MOF) chemistry; part of evolution in perception MOFs from perfect, rigid matrices dynamic materials whose chemistry is shaped as much by imperfections it their molecular components. However, challenges defect characterisation and reproducibility persist and, coupled as-yet opaque role for synthetic parameters formation, deny chemists full potential reticular synthesis. Herein we map broad implications defects have on MOF properties, highlight key explore remarkable ways imperfection enriches chemistry. Engineering into metal-organic frameworks a strategy grant additional properties but there are still reproducibility. Here, this Perspective presents benefits framework field.
