The high risk of CO poisoning justifies the need for indoor air quality control and warning systems based on the detection of low concentrations (ppm‐ppb) of CO. Cobalt corrole complexes selectively bind CO vs. O2, CO2, N2, opening new fields of applications. By combining the CO chemisorption properties of cobalt corroles with the known sorption capacity of MOFs, we hope to obtain high performance sensing materials for CO detection. In addition, the exposed metal sites of MOFs lead to CO2 physisorption, allowing the co‐detection of CO and CO2. In this work, PCN‐222 a stable Zr‐based MOF made from Ni(TCPP) with natural vacancies has been used as a porous matrix for the grafting of electron‐poor metallocorroles. The materials were characterized by powder XRD, SEM and optical microscopy, BET analyses and gas adsorption measurements at 298 K. No degradation of the crystalline structure of PCN‐222 was observed. At 1 atm, the adsorbed CO(g) volumes measured for the best materials were 12.15 cm3 g‐1 and 14.01 cm3 g‐1 for CoCorr2@PCN‐222 and CoCorr3@PCN‐222 respectively, and both materials exhibited high CO chemisorption and selectivity against O2, N2, and CO2 at low pressure due to the highest energy of the chemisorption process vs physisorption.

Framework based compounds for eco‐friendly catalysis is of utmost industrial interest. CuI‐catalyzed “click” reactions are a class of highly efficient and widely used chemical reactions in organic synthesis for potential applications in biotechnology, medicine, polymer, and material sciences. The importance of click chemistry also acknowledge by 2022 Noble Prize in chemistry. One of the most well‐known click reactions is the copper‐catalyzed azide‐alkyne cycloaddition (CuAAC), which is a type of Huisgen 1,3‐dipolar cycloaddition reaction. Herein, three stable copper(I)‐coordination polymers (CPs), [Cu(4‐ABPT)Cl], CP‐1; [Cu(4‐ABPT)Br], CP‐2; [Cu2(4‐ABPT)0.5I2], CP‐3; (4‐ABPT=3,5‐di(pyridine‐4‐yl)‐4H‐1,2,4‐triazol‐4‐amine) have been chosen for CuAAC reaction, due to presence of both Lewis acidic (copper ion), and basic (pyridyl and amine) sites. The counter anion plays a crucial role in their structural motif as well as catalytic efficiency. These easily synthesizable and scalable catalysts exhibit the trend of CP‐1>CP‐2>CP‐3 in catalysis for the selective conversion of phenylacetylene, benzyl bromide, and sodium azide into 1,4‐cycloaddition product within 2 h at ambient temperature and solvent free reaction conditions. CuAAC reaction using catalyst CP‐1 exhibits near quantitative conversion within 2 h at room temperature in solvent free conditions. Herein, we demonstrated the bulk‐scale synthesis of CuI CPs for efficient azide‐alkyne cycloaddition click reaction under mild reaction conditions.
