Optimizing bromide anchors for easy tethering of amines, nitriles and thiols in porous organic polymers towards enhanced CO2 capture

Novel benzimidazole-linked microporous conjugated polymers for highly selective adsorption and photocatalytic reduction of diluted CO2

“…9 Here, we studied the CO 2 and N 2 uptake capacity and selectivity of the polymers at 273 and 298 K. As shown in Fig. 1c, at 273 K under 1 bar, the CO 2 uptake of TFPT-DAB (53.21 cm 3 g −1 ) is higher than that of TFPA-DAB (44.82 cm 3 g −1 ) and comparable to that of many excellent polymer absorbents such as COP-190H-deta (60.48 cm 3 g −1 ), 35 TNHCP1 (64.74 cm 3 g −1 ), 36 PMDI-cage 1a (65.18 cm 3 g −1 ), 37 and co-CXF3-OPr (53.76 cm 3 g −1 ). 38 The high CO 2 adsorption of TFPT-DAB can be attributed to the synergism of the Lewis basic 1,3,5-triazine and imidazole-building units in the polymer.…”

“…S5 †). [32][33][34][35] Thermogravimetric analysis (TGA) of TFPA-DAB and TFPT-DAB under N 2 indicated that both polymers were highly stable even at 400 °C and yielded >70 wt% char up to 600 °C (Fig. S6 †).…”

Hollow Microporous Organic Polymer@Hypercrosslinked Polymer Catalysts Bearing N-Heterocyclic Carbene–Iron Species for the Synthesis of Biomass-Derived Polymer Platforms

“…The solid-state 13 C NMR spectra of HCP and HMOP@ HCP-2 showed 13 C peaks at 145−112, 43, and 32 ppm, corresponding to aromatic carbons, benzyl carbons, and CH 2 moieties of −CH 2 Br, respectively (Figure 6c,d). 39 After the introduction of imidazolium rings, new 13 C peaks appeared at 52 and 35 ppm, corresponding to CH 2 and CH 3 moieties adjacent to imidazolium rings, respectively, 40 with overlapped aromatic peaks at 145−112 ppm (Figure 6c,d). After iron coordination, peaks became broader at 50 and 35 ppm with broad aromatic peaks at 148−110 ppm (Figure 6c,d).…”

Novel Carbazole-Based Porous Organic Polymer for Efficient Iodine Capture and Rhodamine B Adsorption

“…As a branch of porous materials, porous organic polymers (POPs) have developed rapidly in the adsorption direction for the past few years. Compared with other common porous materials, POPs have the characteristics of high specific surface area, good stability, , and easy structure regulation and functionalization, , which can greatly improve the adsorption capacity and removal rate. In addition, high affinity binding sites − can be embedded in the skeleton when designing POPs according to the target, such as introducing a large number of heteroatoms (F, S, N, etc.…”
