FredrikB jçrnerbäck andN iklas Hedin* [a] Highly porousa nd hyper-cross-linked polymers (HCPs) have a range of applications and are typicallys ynthesized in an unsustainable manner.H erein, HCPs were synthesized from abundant biobased or biorelatedc ompounds in sulfolane with iron(III) chloride as Lewis acid catalyst. As reactants, quercetin, tannic acid, phenol, 1,4-dimethoxybenzene, glucose, and a commercial bark extract wereu sed. The HCPs had high CO 2 uptake (up to 3.94 mmol g À1 at 0 8Ca nd 1bar), total pore volumes (up to 1.86 cm 3 g À1 ), and specific surfacea reas (up to 1440 m 2 g À1 ). 1 HNMR, 13 CNMR, and IR spectroscopy,w ideangle X-ray scattering, elementala nalysis, and SEM revealed, for example, that the HCPs consisted of amorphous and crosslinked aromatic and phenolic structures with significant contents of aliphatics, oxygen, and sulfur.[a] Dr.

“…This interesting phenomenon might arise from the presence of polar IL units within the organic frameworks, thus the strong interaction resulted in a decreased BET surface area during the synthetic process . Additionally, if we consider the high atomic mass of the bromide ion, it is understandable that the abundant bromide anions in the micropore structure of POPs might result in the decrease of the surface area after modification . We used nonlocal density functional theory (NLDFT) to calculate the pore size distribution (PSD) of Al‐POP, Al‐iPOP‐1, and Al‐iPOP‐2, which suggested the presence of narrow micropores in the range of 1.2–1.4 nm (Figure B).…”

Charged Metalloporphyrin Polymers for Cooperative Synthesis of Cyclic Carbonates from CO₂ under Ambient Conditions

et al. 2017

A facile and one-pot synthesis of metalloporphyrin-based ionic porous organic polymers (M-iPOPs) was performed through a typical Yamamoto-Ullmann coupling reaction for the first time. We used various characterization techniques to demonstrate that these strongly polar Al-based materials (Al-iPOP) possessed a relatively uniform microporosity, good swellable features, and a good CO capture capacity. If we consider the particular physicochemical properties, heterogeneous Al-iPOP, which bears both a metal active center and halogen anion, acted as a bifunctional catalyst for the solvent- and additive-free synthesis of cyclic carbonates from various epoxides and CO with an excellent activity and good recyclability under mild conditions. Interestingly, these CO -philic materials could catalyze the cycloaddition reaction smoothly by using simulated flue gas (15 % CO in N , v/v) as a raw material, which indicates that a stable local microenvironment and polymer swellability might promote the transformation. Thus, the introduction of polar ionic liquid units into metalloporphyrin-based porous materials is regarded as a promising new strategy for the chemical conversion of CO .

“…The emission of CO 2 , in turn, leads to serious environmental and economic problems globally [4][5][6]. The high CO 2 level is the main cause of global warming, climate changes, rise in sea and ocean levels, and increased acidity of CO 2 is the development of an efficient synthetic procedure that does not involve the use of metal catalysts, production of high surface area POPs that have 3D structures, the use of efficient and moderate reaction conditions within the post-synthetic procedures, and the use of POPs that have multiple adsorption sites to the capacity of CO 2 adsorption at very low pressures [30].…”

Synthesis of Novel Heteroatom-Doped Porous-Organic Polymers as Environmentally Efficient Media for Carbon Dioxide Storage

et al. 2019

The high carbon dioxide emission levels due to the increased consumption of fossil fuels has led to various environmental problems. Efficient strategies for the capture and storage of greenhouse gases, such as carbon dioxide are crucial in reducing their concentrations in the environment. Considering this, herein, three novel heteroatom-doped porous-organic polymers (POPs) containing phosphate units were synthesized in high yields from the coupling reactions of phosphate esters and 1,4-diaminobenzene (three mole equivalents) in boiling ethanol using a simple, efficient, and general procedure. The structures and physicochemical properties of the synthesized POPs were established using various techniques. Field emission scanning electron microscopy (FESEM) images showed that the surface morphologies of the synthesized POPs were similar to coral reefs. They had grooved networks, long range periodic macropores, amorphous surfaces, and a high surface area (SBET = 82.71–213.54 m2/g). Most importantly, they had considerable carbon dioxide storage capacity, particularly at high pressure. The carbon dioxide uptake at 323 K and 40 bar for one of the POPs was as high as 1.42 mmol/g (6.00 wt %). The high carbon dioxide uptake capacities of these materials were primarily governed by their geometries. The POP containing a meta-phosphate unit leads to the highest CO2 uptake since such geometry provides a highly distorted and extended surface area network compared to other POPs.
