“…At 273 K and 1 bar, PMOP-Si could uptake 138.9 mg g −1 of CO 2 . The value of 138.9 mg g −1 is superior to those reported for prior reported MOPs, including Porp-TPE-CMP (88.7 mg g −1 , S BET = 547 m 2 g −1 ), 37 ANOP-2 (101.8 mg g −1 , S BET = 638 m 2 g −1 ), 45 PCMOP-H1 (121 mg g −1 , S BET = 675 m 2 g −1 ), 46 and PCN-TCP (130 mg g −1 , S BET = 757 m 2 g −1 ). 6 Additionally, the CO 2 uptake obtained by the PMOP-Si also competes with many microporous organic polymers, such as PMOPs (121.9–160.1 mg g −1 ), 3 POPs (90–145 mg g −1 ), 47 and TMPs (103–157 mg g −1 ).…”

“…Nonetheless, under ambient conditions, CNOP-2 adsorbed C 2 H 6 at a capacity of 71.0 cm 3 /g, which is considerably more than those of reported porous materials, including PNOP-1 (47.1 cm 3 /g), MCOF-1 (44 cm 3 /g), PAN-T1 (49.8 cm 3 /g), and LIFM-W2 (28.5 cm 3 /g) . Furthermore, CNOPs that feature carbazole fragments exhibited high CO 2 uptakes of 84.2–90.2 cm 3 /g at 1 bar and 273 K that are inferior to those of the reported CNOPs, as shown in Table S1, such as CPOPs (39.7–67.2 cm 3 /g), Car-TPA COF (62.6 cm 3 /g), PCMOP-H1 (61.6 cm 3 /g), and SCHPP-2 (40.1 cm 3 /g) . In addition, this value exceeded those of other reported NOPs, such as PANs (67.1–83.6 cm 3 /g), sPIs (54.4–67.4 cm 3 /g), PBOs (48.9–59.1 cm 3 /g), and ANOPs (32.5–51.8 cm 3 /g) .…”

The Friedel–Crafts (FC) reaction is a prominent synthetic tool for rapidly constructing complex molecular frameworks, but syntheses of carbazole-based nanoporous organic polymers (CNOPs) via FC hydroxyalkylation are rare. Herein we report the acid-catalyzed FC hydroxyalkylation synthesis of two CNOP networks, prepared (using p-phthalaldehyde) from 1,3,5-tris(9-carbazolyl)benzene and tris[4-(9H-carbazol-9-yl)phenyl]amine. The specific surface areas of the CNOPs ranged from 1374 to 1546 m2/g, and the CNOPs had a hierarchical porous structure with pore sizes ranging from 0.87 to 6.60 nm. Furthermore, the high porosity in conjunction with abundant carbazole units in the CNOPs enabled excellent adsorption performance toward C2H6, CO2, and CH4. CNOP-2 derived from 1,3,5-tris(9-carbazolyl)benzene and p-phthalaldehyde displayed C2H6, CO2, and CH4 uptakes of up to 98.7, 90.2, and 30.7 cm3/g, respectively, at 1 bar and 273 K. Also, the adsorption selectivities of the CNOPs in conjunction with C2H6/CH4 and CO2/CH4 gas mixtures were 23.4–23.5 and 6.4–7.3, respectively. This work demonstrates a cost-effective FC reaction that can be used to design and construct carbazole-based nanoporous organic polymers.

“…On the other hand, carbazole and its derivatives are used as organic monomers to prepare POPs via FeCl 3 -promoted oxidative coupling polymerization due to the large-conjugated system, rigid structure, high reactivity, and excellent photoelectric properties of carbazole and its derivatives. Thus, some carbazole-based POPs have been synthesized and implemented in diverse fields [ 34 , 35 , 36 ].…”

Design and Construction of an Azo-Functionalized POP for Reversibly Stimuli-Responsive CO2 Adsorption

2023

View full text Add to dashboard Cite

A porous azo-functionalized organic polymer (JJU-2) was designed and prepared via oxidative coupling polymerization promoted by FeCl3. JJU-2 exhibited reversibly stimuli-responsive CO2 adsorption properties as a result of the trans/cis isomerization of the polymer’s azo-functionalized skeleton. Under UV irradiation and heat treatment, this porous material displayed various porous structures and CO2 adsorption properties. The initial Brunauer-Emmett-Teller (BET) surface area of JJU-1 is 888 m2 g−1. After UV irradiation, the BET surface area decreases to 864 m2 g−1, along with the decrease of micropores around 0.50 nm and 1.27 nm during the trans-to-cis isomerization process. In addition, CO2 sorption isotherms demonstrate an 8%t decrease, and the calculated Qst of CO2 has decreased from 29.0 kJ mol−1 to 26.5 kJ mol−1 due to the trans to cis conversion of the azobenzene side group. It is noteworthy that JJU-2′s CO2 uptakes are nearly constant over three cycles of alternating external stimuli. Therefore, this azo-functionalized porous material was a potential carbon capture material that was responsive to stimuli.
