Synthesis of Porous Organic Polymers Via Catalytic Vapor-Assisted Solvent-Free Method

Abstract: Solvent-free synthesis is one kind of important approach for the preparation of porous materials. However, the catalytic vapor generated during these processes is limitedly reported. Herein, a novel catalytic vapor-assisted solvent-free method was established for the preparation of porous organic polymers (POPs) by application of catalytic vapor derived from ferric chloride. After investigating the decisive factors of this approach, its versatility is examined by synthesizing POPs from multitudinous monomers. … Show more

“…CNOP-6 exhibited higher Brunauer–Emmett–Teller (BET) surface areas than previously reported porous polymers, such as PNOPs (729–830 m 2 ·g –1 ), ANOPs (1052–1272 m 2 ·g –1 ), sPANs (65–113 m 2 ·g –1 ), TpPa-F (1048 m 2 ·g –1 ), and NUSs (582–720 m 2 ·g –1 ) . CNOP-6 also demonstrated competitiveness with previously reported CNOPs, including CNOP-5 (1425 m 2 ·g –1 ), CNOPs (1374–1546 m 2 ·g –1 ), CNOPs (769–1007 m 2 ·g –1 ), and CPOP1-V3 (1210 m 2 ·g –1 ) . The pore-size distribution of CNOP-6, as depicted in Figure b, was determined through nonlocal density functional theory.…”

“…19 CNOP-6 also demonstrated competitiveness with previously reported CNOPs, including CNOP-5 (1425 m 2 •g −1 ), 15 CNOPs (1374−1546 m 2 •g −1 ), 16 CNOPs (769−1007 m 2 • g −1 ), 17 and CPOP1-V3 (1210 m 2 •g −1 ). 22 The pore-size distribution of CNOP-6, as depicted in Figure 2b, was determined through nonlocal density functional theory. The primary pore size of CNOP-6 was observed to be 0.41 nm, which corresponds to the microporous region based on N 2 adsorption isotherms at 77 K. The presence of a wide distribution in the range of 2−50 nm suggests the existence of a mesoporous structure.…”

“…33 The S BET values measured for ANOP-4 were similar to those reported for other NOPs, such as PAN-1 (925 m 2 g −1 ), 34 PCN-TCP (751 m 2 g −1 ), 35 POPTrB-4F (776 m 2 g −1 ), 36 and CPOP1-V2 (1150 m 2 g −1 ). 37 Additionally, the total pore volumes for ANOP-3 and ANOP-4 were determined, from the N 2 sorption isotherms at P / P 0 = 0.99, to be 0.186 and 0.789 cm 3 g −1 , respectively. The microporous surface area and volumes, evaluated using the t -plot method, were found to be 217 m 2 g −1 and 0.109 cm 3 g −1 , respectively, for ANOP-3 , and 792 m 2 g −1 and 0.392 cm 3 g −1 , respectively, for ANOP-4 .…”

“…Porous organic polymers (POPs), benefiting from the stability advantage and structural designability, offer new electronic functionality not available in inorganic materials toward electron devices. Promising examples of novel characteristics in organic devices range from the memory effects observed in polymer films to nonvolatile memristors. So far, although a microscopic understanding of the conduction mechanisms and switching materials of memristors is developing, the study of memristors based on POPs as switching materials is lacking due to the existence of huge challenges in film preparation . Carbazole-based POPs (CPOPs) have recently been developed through oxidative polymerization as an emerging POP possessing potential in semiconductor-related applications. Differing from most POPs prepared as the powder forms, CPOPs possess the ability to be prepared in films directly via an electrochemical polymerization strategy. Generally, benefiting from the relatively low oxidative and reduction potential, carbazole units in monomers are transformed into radicals and dimeric carbazole cations under the promotion of applied oxidative potential, and then, radicals and dimeric carbazole cations are reduced to neutral forms under the stimulation of applied reductive potential. Eventually, electropolymerized porous films can be formed with polymerization extension via the alternation of oxidation and reduction potentials. Specifically, the development of electrochemical synthesis techniques addresses the nonprocessable nature of POPs.…”
