“…The Q st values of the NRPPs are within close proximity of the optimum value for CO 2 capture from flue gas (∼33 kJ mol –1 ), as previously postulated in the literature. The CO 2 uptakes of NRPP-1 and NRPP-2 are among the highest of other nitrogen-rich polymers, including BILPs, ,− ALPs, , azo-COPs, and PECONFs …”

The use of fossil fuels for energy production is accompanied by carbon dioxide release into the environment causing catastrophic climate changes. Meanwhile, replacing fossil fuels with carbon-free nuclear energy has the potential to release radioactive iodine during nuclear waste processing and in case of a nuclear accident. Therefore, developing efficient adsorbents for carbon dioxide and iodine capture is of great importance. Two nitrogen-rich porous polymers (NRPPs) derived from 4-bis-(2,4-diamino-1,3,5-triazine)-benzene building block were prepared and tested for use in CO and I capture. Copolymerization of 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with terephthalaldehyde and 1,3,5-tris(4-formylphenyl)benzene in dimethyl sulfoxide at 180 °C afforded highly porous NRPP-1 (SA = 1579 m g) and NRPP-2 (SA = 1028 m g), respectively. The combination of high nitrogen content, π-electron conjugated structure, and microporosity makes NRPPs very effective in CO uptake and I capture. NRPPs exhibit high CO uptakes (NRPP-1, 6.1 mmol g and NRPP-2, 7.06 mmol g) at 273 K and 1.0 bar. The 7.06 mmol g CO uptake by NRPP-2 is the second highest value reported to date for porous organic polymers. According to vapor iodine uptake studies, the polymers display high capacity and rapid reversible uptake release for I (NRPP-1, 192 wt % and NRPP-2, 222 wt %). Our studies show that the green nature (metal-free) of NRPPs and their effective capture of CO and I make this class of porous materials promising for environmental remediation.

“…Here, unlike other polymerization methods, the reaction of excess solvent linkers leads to richer surface chemistry with dangling species. Unreacted halogens may contribute to CO 2 uptake, [31] although lesser than the remnant oxygens that are introduced by their hydrolysis. We believe that the oxygenated surfaces of COPs produced here are responsible for their superior CO 2 www.advancedsciencenews.com www.advenergysustres.com performance.…”

Porous solids with high surface areas, thermal stability, and chemically robust nature have attracted great attention because of their applications in gas capture and storage, [1] water treatment, [2] and catalysis. [3] In addition to the commonly used porous materials in the industry such as zeolites, activated carbons, and molecular sieves, recent developments show that various classes of new porous solids have emerged, such as metal organic frameworks (MOFs), [4] covalent organic frameworks (COFs), [5] covalent organic polymers (COPs), [6] hypercross-linked polymers (HCPs), [3e,7] microporous organic polymers (MOPs), [8] porous aromatic frameworks (PAFs), [9] porous polymer networks (PPNs), [10] and benzimidazole-linked polymers (BILPs). [11] To be used in industrial scale, these materials are expected to be highly porous, thermally and chemically robust, and easily synthesized from inexpensive precursors. Although numerous materials have been reported so far, most have drawbacks such as difficult synthetic procedures, expensive and complex starting monomers, or require rare earth metals. So far, only a handful of these porous materials have proven relatively scalable with affordable synthesis. [12] Considering the availability of the precursors and reagents, Friedel-Crafts (FC) alkylation [13] is one of the most promising

“…The porosity of COP-220 was studied by N 2 physisorption measurements at 77 K (Figure c). It was found to be mainly microporous with a commonly observed hysteresis due to the delay of the probe gas in exiting the microporous framework . The Brunauer–Emmett–Teller (BET) surface area was 487 m 2 g –1 , and the total pore volume was 0.182 cm 3 /g.…”

A new, high surface area, nanoporous polymer (COP-220) was synthesized using sustainable building blocks, namely, a food coloring dye (erythrosine B) and a commercial alkyne. During the Sonogashira coupling, it is observed that Pd and Cu ions and triphenylphosphine ligands of the catalyst get trapped inside the pores. The remnant synthesis catalyst components were characterized in detail and were tested as a new catalyst for Suzuki–Miyaura coupling reactions. COP-220 showed conversion yields comparable to the commercial homogeneous catalyst Pd(PPh3)2Cl2 with an additional advantage of size-dependent catalytic activity when bulkier substrates were used. COP-220 was highly stable under thermal and chemical treatments and recyclable with no loss of activity. These findings show a clear need for extensive characterization of nanoporous polymers made through cross-coupling reactions and the potential of the trapped catalysts for new catalytic activity without additional loading.
