“…2 and Supplementary Information) 25 . An scanning electron microscopy (SEM) image of 1 showed irregular particles, and the individual particles were composed of aggregated ~15-nm primary nanoparticle (Supplementary Fig.…”

Porous Organic Polymers Constructed from Tröger's Base as Efficient Carbon Dioxide Adsorbents and Heterogeneous Catalysts

“…At 273 K, POP‐TB and POP‐Me‐TB can absorb 90 and 71 mg g −1 of CO 2 at a pressure up to 1 bar of pure CO 2 , and the uptake is reduced to 60 and 44 mg g −1 , respectively, if the temperature is increased to 298 K (Figure ). These values are comparable to those reported previously (Table S1) . The relatively higher adsorption capacity of POP‐TB than that of POP‐Me‐TB is reasonably attributed to the higher pore volume of POP‐TB (0.49 cm 3 g −1 ) than that of POP‐Me‐TB (0.36 cm 3 g −1 ), as demonstrated by the N 2 sorption isotherm.…”

“…[16] Porous organic polymers (POPs), which have stable covalent bondsa nd alwaysp ossess an excellent stability,l arge pore volume, high surface area, and designable structure, are an emerging class of porousm aterials. [17] Recently,o ur group has reported as eries of porouso rganic ligands( POLs)s ynthesized through solvothermal radicalp olymerization methods from the corresponding vinyl-functionalized ligand monomers themselves, for which the concentration of organic ligandsw as maximized because of the composition of the porouspolymers with pure organic ligands. For example, if we used vinyl-functionalized diphosphine monomers (v-dppe), aP OP called POLdppe was synthesized.…”
