Strategic design of solid-state proton-conducting electrolytes for application in anhydrous proton-exchange membrane fuel cells (PEMFCs) has gained burgeoning interest due to a spectrum advantageous features, including higher CO tolerance and ease the water management systems. Toward this direction, crystalline materials like metal-organic frameworks (MOFs), covalent organic (COFs), hydrogen-bonded (HOFs), polyoxometalates (POMs) are emerging PEM materials, offering strategic structural engineering through crystallography, thus enabling ultrahigh proton conductivity up 10-2-10-1 S/cm. This Perspective highlights significant progress achieved far with such platforms domain conduction across wide temperature window (sub-zero above 100 °C). Based on their backgrounds, these categorized into four classes (viz. MOFs, COFs, HOFs, POMs) detailed evolutionary timeline since emergence early 2009. Insightful discussions key focus strategies undertaken attain along implementation cell technology electrode assembly presented. A section "Critical Analysis Future Prospects" provides decisive viewpoints those overlooked issues future endorsement (e.g., performance assessment analysis test stand) further development while comparing them other from both academic industrial perspectives.

Abstract Despite possessing numerous catalytic advantages of MOFs, developing 2D frameworks having excellent chemical stability along with new properties remains a grand challenge. Herein, by employing mixed ligand synthetic approach, we have constructed Ni‐MOF, IITKGP‐52 , which exhibits framework robustness in open air, water, as well over wide range aqueous pH solutions (2–12). Benefitting from its and abundant Lewis acidic metal sites (OMSs), is explored catalyzing the heterogeneous three‐component condensation reaction for tandem synthesis bioactive 2‐amino‐3‐cyano‐4H‐pyran derivatives low loading, greater compatibility substrates, recyclability superior efficiency than previously employed homo systems. inaugurates employment MOF‐based catalysts one‐pot therapeutic derivatives.

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
