Abstract Misuse of antibiotics and pesticides has led to hazardous effects on human health, livestock, agriculture, aquaculture, which urges researchers find simple, rapid, efficient, cost‐effective methods for quick on‐site analysis these organic pollutants with functional materials. Herein, a 2D chemically robust MOF: IITKGP‐71 , {[Cd(MBPz)(2,6‐NDC)]·2H 2 O} n is strategically developed ease in scalability exploited as dual sensors toward the toxic antibiotic pesticide detection via luminescence quenching aqueous medium . The framework displays exceptional chemical robustness water 3 months, an open atmosphere over wide range pH solution (pH = 3–12) day. can selectively quench nitrofuran (NFZ NFT) organochlorine DCN while remaining unaffected by other interfering pesticides, respectively. An excellent trade‐off between high effectivity (high K sv ) sensitivity (low LOD) was achieved targeted analytes. easy scalability, stability, fast responsivity, multi‐responsive nature, recyclability outstanding structural stability made this viable playing crucial role safeguarding aquatic ecosystems public health from pesticides.

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. Most importantly, reaction, three bioactive diindolylmethane (DIM) core are first time, was never realized any sort heterogeneous catalysts. Moreover, Arundine crystallized an in‐depth crystallographic analysis performed. The excellent framework robustness highlight potentiality developed unwrap new avenue molecule

The increasing impact of elevated atmospheric CO2 levels on climate and biological systems underscores the urgent need for effective materials to mitigate these concentrations. Simultaneously, demand quinoline derivatives has risen sharply due their critical role in synthesizing life-saving drugs. Here, we present synthesis, characterization, catalytic activity an aqua-stable Al(III) metal-organic framework (MOF 1') its postmodified variant doped with Ag(0) nanoparticles (1'-Ag NPs). native MOF (1') nanoparticle-anchored derivative exhibited remarkable efficacy two key areas: quantitative synthesis heterocycles irreversible chemical fixation into various alkynes. Under ambient temperature pressure, 1'-Ag NPs demonstrated exceptional performance cyclization propargylic alcohols. Moreover, catalysts excellent recyclability across multiple reusability cycles.
