Abstract Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic and persistent organic pollutants in water. Their removal is highly challenging for existing generic nonspecific adsorbents, creating an urgent need tailored solutions. Herein, a metal‐“organic cage” framework, MOF‐CC‐1 , designed the effective scavenging of PAHs from water introduced. This framework constructed using propeller‐shaped cofacial cage ( CC‐1 ), equipped with three triazole pillars that coordinate Ag(I) ions. The cationic adopts chiral (10,3)‐a srs net structure, spontaneously resolving into homochiral crystals. Additionally, bulk homochirality achieved through chirality induction counteranions. uniquely encapsulates diverse PAH molecules within cavities CC‐1, as confirmed by single‐crystal X‐ray diffraction, marking it first metal–“organic structural evidence guest inclusion inside linker. Further, exhibits soft porosity, remaining nonporous to N₂ gas when compressed but expanding encapsulate solution. Moreover, exceptional efficacy ppb levels work represents significant advancement utilizing cages ligands toward MOF construction, paving way adsorbents removal, addressing critical selective efficient materials environmental remediation.

Abstract Synthesis of biologically and pharmaceutically important drugs via organic transformations in one pot under mild conditions with efficient catalysts is significant interest terms practical utility. Though metal‐organic frameworks (MOFs) prove their efficiencies various catalytic reactions, synthesis drug molecules employing MOF still its early stage, fact, restricted to only 1,4‐Dihydropyridines (1,4‐DHP) based synthesis. Although the Friedel–Crafts alkylation (FCA) reaction oldest reactions a impact on synthesis, surprisingly this triggered by catalyst largely unexplored. Herein, we report robust framework, MO F : IITKGP‐55 , synthesized solely aqueous medium which exhibits superior for one‐pot FCA well tolerance substrate scopes.
