“…It was established that the building units show crucial effects on the porosity, specific surface areas, and gas adsorption capacities of the final porous organic polymers. 2D and 3D conjugated architectures with non‐planar rigid conformation, such as [2.2]paracyclophan, triphenylamine, triphenylbenzene, and tetraphenylethylene (TPE), have been proven to be good candidates for the monomer core structure to form microporous polymers with permanent porosity and special functions. Carbazolyl groups can be easily introduced into these monomer core structures to afford versatile building units for porous polymer preparation.…”

Facile preparation of microporous conjugated polycarbazoles via carbazole-based oxidative coupling polymerization is reported. The process to form the polymer network has cost-effective advantages such as using a cheap catalyst, mild reaction conditions, and requiring a single monomer. Because no other functional groups such as halo groups, boric acid, and alkyne are required for coupling polymerization, properties derived from monomers are likely to be fully retained and structures of final polymers are easier to characterize. A series of microporous conjugated polycarbazoles (CPOP-2-7) with permanent porosity are synthesized using versatile carbazolyl-bearing 2D and 3D conjugated core structures with non-planar rigid conformation as building units. The Brunauer-Emmett-Teller specific surface area values for these porous materials vary between 510 and 1430 m(2) g(-1) . The dominant pore sizes of the polymers based on the different building blocks are located between 0.59 and 0.66 nm. Gas (H2 and CO2 ) adsorption isotherms show that CPOP-7 exhibits the best uptake capacity for hydrogen (1.51 wt% at 1.0 bar and 77 K) and carbon dioxide (13.2 wt% at 1.0 bar and 273 K) among the obtained polymers. Furthermore, its high CH4 /N2 and CO2 /N2 adsorption selectivity gives polymer CPOP-7 potential application in gas separation.

“…5.16b). Since then, various synthetic strategies have been used to synthesize CMPs, such as Yamamoto [132][133][134][135][136], Ullmann [137], Suzuki [138][139][140][141][142][143][144][145], Sonogashira-Hagihara coupling [146][147][148][149][150][151][152], oxidative coupling [145,153], and ethynyl cyclotrimerization [154][155][156]. As a result, the CMPs family was expanded quickly in the last several years.…”

Microporous organic polymers (MOPs) are a unique class of porous materials consisting solely of the light elements (C, H, O, N, etc.). A series of vivid characteristics of MOPs, such as high-specific surface area, good physicochemical stability, diverse pore dimensions, topologies, and chemical functionalities, make them suitable adsorbents for CO 2 capture. In this chapter, MOPs are categorized into four classes according to the types of organic reactions and the chemical structures of the resulting materials: hypercrosslinked polymers (HCPs), covalent organic frameworks (COFs), polymers of intrinsic microporosity (PIMs), and conjugated microporous polymers (CMPs). For each type of the polymer network, the state-of-the-art development in the design, synthesis, characterization, and the CO 2 sorption performance is reviewed. Strategies for controlling CO 2 uptake capacity and adsorption enthalpy via manipulation of surface area, pore size, and functionality are discussed in detail. These studies would open up many new possibilities for the development of the novel solid sorbents targeting the CO 2 capture process. It is expected that this chapter will not only summarize the main research activities in this field, but also find possible links between basic studies and practical applications.

“…Microporous conjugated polymers with a narrow pore distribution may interact attractively with small gas molecules through improved molecular interaction (23,24). Furthermore, electron-rich spiro(fluorene-9,9 0 -xanthene) network and high charge density at the oxygen sites of the polymer might facilitate more favorably the interaction between sorbate molecule and adsorbent (5).…”

Spiro(fluorene-9,9 0 -xanthene)-based polymeric monodisperse spheres have been prepared through a surfactant-free Suzuki coupling polymerization in a single-phase. The polymer (PSFX) exhibits permanent microporous nature with Brunauer-Emmett-Teller specific surface area up to 610 m 2 g ¡1 . Its hydrogen storage can reach to 1.20 wt% (1.0 bar and 77 K) and the uptake capacity for carbon dioxide is 11.8 wt% (1.0 bar and 273 K). PSFX is a highly hydrophobic material with good sorption capacity for toluene (887 mg g ¡1 at saturated vapor pressure and room temperature), which makes it show potential use in elimination of harmful small aromatic molecules in the environment. Interestingly, PSFX exhibits a remarkable fluorescent emission property in the suspension. Fluorescence detection of explosive chemical (TNT) was performed through a series of spectrofluorometric titration using the suspension of PSFX as the probe.
