Abstract Porous polymer show great potential for CO 2 capture owing to its high specific surface area, adjustable porous structure and chemical structure. Herein, a novel adsorption materials ALP−M (M: Cu 2+ , Mg Ni ) were prepared through coordination between azo‐linked (ALP) synthesized by oxidative coupling polymerization of tris(4‐aminophenyl)amine metal ions. The structures morphology as‐prepared demonstrated FT‐IR, XRD, XPS, BET SEM, the performance mechanism also investigated static column experments, results that ions can enhance desorption ALPs adsorption. showed highest capacity 2.67 mmol g −1 at 273 K (1 bar), which is 35.5 % higher than ALP. served as Lewis acid sites affinity adsorbent . In experiments, saturated 4.99 bar) adsorption, excellent cycling stability after 500 cycles, retention rate reach 98 %.

Nitrogen-doped carbon materials, characterized by abundant microporous and nitrogen functionalities, exhibit significant potential for dioxide capture supercapacitors. In this study, a class of porous organic polymer (POP) were successfully synthesized linking Cr-TPA-4BZ-Br4 tetraethynylpyrene (Py-T). The model benzoxazine monomers Cr-TPA-4BZ using the traditional three-step method [involving CH═N formation, reduction NaBH4, Mannich condensation]. Subsequently, Sonogashira coupling reaction connected Py-T monomers, forming Cr-TPA-4BZ-Py-POP. successful synthesis Cr-TPA-4BZ-Py-POP was confirmed through various analytical techniques. After verifying Cr-TPA-4BZ-Py-POP, carbonization KOH activation procedures conducted. These crucial steps led to formation poly(Cr-TPA-4BZ-Py-POP)-800, material with structure akin graphite. practical applications, poly(Cr-TPA-4BZ-Py-POP)-800 exhibited noteworthy CO2 adsorption capacity 4.4 mmol/g, along specific capacitance values 397.2 159.2 F g–1 at 0.5 A (measured in three-electrode cell) 1 symmetric coin cell), respectively. exceptional dual capabilities stem from optimal ratio heteroatom doping. outstanding performance holds promise addressing contemporary energy environmental challenges, making substantial contributions both sectors.

We investigated the performance that is improved in various applications through molecular structural alterations. Specifically, we emphasized importance of controlling branching densities organic moieties as a useful tactic for varying surface area and porosity hybrid porous organic/inorganic polymers (HPPs), which include octavinylsilsesquioxane (OVS) units. This study shows adjusting could greatly enhance energy storage hydrogen production. The two-branched chemical structure (4,7-dibromo-2,1,3-benzothiadiazole, BT-Br2) four-branched compound (1,1,2,2-tetrakis(4-bromophenyl)ethylene, TPE-Br4) are individually reacted with OVS 1,3,6,8-tetrabromopyrene (Py-Br4) twice to prepare HPPs. These materials high or low cross-linking density, well small large areas, synthesized by this dual reaction, also produces HPPs different densities. Based on Brunauer–Emmett–Teller calculations, OVS-Py-BT HPP has more than 4.5 times larger OVS-Py-TPE material. Remarkably, exhibited exceptional results supercapacitor applications, specific capacitance values 248 54 F/g HPPs, respectively, determined galvanostatic charge–discharge. significantly outperformed photocatalytic evolution. evident from their respective evolution rates: 1348 μmol g–1 h–1 much lower 11.3 HPP.
