A simple and cost-effective synthesis of ionic porous organic polymers with excellent porosity for high iodine capture

Facile Preparation of Cost‐Effective Triphenylamine‐Based Nanoporous Organic Polymers for CO2, I2, and Organic Solvents Capture

“…[ 22 ] 131 mg g ‒1 for i‐POP‐BP‐BPTM‐3 ( S BET = 1485 m 2 g ‒1 ). [ 23 ] ANOP‐2 shows higher CO 2 uptake than ANOP‐1 because of higher microporous surface areas and microporous volume than ANOP‐1. The ANOPs show high CO 2 uptake due mainly to their large microporous surface areas and volumes and their dense TPA moiety.…”

“…As observed in Figure b, the adsorption amount of iodine for ANOPs increased gradually and reached saturation after 30 h. The I 2 adsorbed uptakes of ANOP‐1 and ANOP‐2 were 3111 and 3209 mg g ‒1 . The value of 3209 mg g ‒1 I 2 vapor uptake is less than those of the reported porous polymers, such as TTA‐FMTA‐COF(6110 mg g ‒1 , 350 K), [ 25 ] TTA‐FMTA‐COF(5070 mg g ‒1 , 350 K), [ 26 ] MeBID[3] (4950 mg g ‒1 , 348 K), [ 27 ] TTA‐TTB COF (4950 mg g ‒1 , 350 K), [ 28 ] i‐POP‐BPTM‐3(4150 mg g ‒1 , 350 K), [ 23 ] amorphous porous organic polymers (ADB‐S 342 mg g ‒1 , 348 K). [ 29 ] Moreover, the values are superior to those of other reported NOPs, as seen in Table S1 (Supporting Information), such as hyper cross‐linked polymers (HCP‐PNs, 1560–1900 mg g ‒1 , 353 K), [ 30 ] covalent triazine‐based framework (TTPBTA, 1640 mg g ‒1 , 350 K), [ 31 ] conjugated microporous polymers (SCMPs, 1880–2220 mg g ‒1 , 353 K), [ 32 ] and porous aromatic framework (PAF‐24, 2760 mg g ‒1 , 348 K).…”

Neutral and Cationic Phenothiazine‐Based Porous Organic Polymers via a Simple and Cost‐Effective Method for Iodine Capture

“…The PTA‐POP@I 2 (Figure 4a) and C‐PTA‐POP@I 2 (Figure 4b) complex showed both neutral I 2 and anion I 3 − information, which indicated some iodine molecules were transformed into I 3 − . These results revealed physical and chemical adsorption occurred in the process [4–6,37] . Compared to the PTA‐POP@I 2 , the C‐PTA‐POP@ I 2 complex indicated a high conversion rate from neutral I 2 to anion I 3 − .…”

“…In this system, some iodine molecules were converted into I 3 − and I 5 − to improve the capture ability of iodine. Although C‐PTA‐POP possessed lower porosity than PTA‐POP, cationic units produced strong electrostatic interactions between the positively charged NH 2 groups and iodine to enhance uptake value [15, 23,37] …”

“…Comparing traditional inorganic porous materials, porous organic polymers (POPs) are a new class of porous material to offer various advantages including high porosity, permanent pore structure, and special stability. In recent years, POPs have been a rapid development give notable examples as conjugated microporous polymers (CMPs), [7] polymers of intrinsic microporous (PIMs), [8] covalent organic frameworks (COFs), [9] porous aromatic frameworks (PAFs), [10] and hypercrosslinked polymers (HCPs), [11] which achieves multi‐functions including gas storage, chemical sensor, catalyst, energy field, and pollutants removal [9–37] …”
