“…For instance, nitrogen-rich conjugated microporous polymers (N-CMPs) and nitrogen-rich azo-bridged porphyrin conjugated microporous networks (N-Azos) have been synthesized and yielded S BET up to 485 and 675 m 2 /g with H 2 uptake of 1.02 and 1.15 wt % respectively at 77K/1bar [100,101]. Thiophene-based conjugated microporous polymers (ThPOPs) have been synthesized and tested for H 2 storage [102]. Among them, ThPOP-5 that retains both high BET surface ( S BET = 1300 m 2 /g) and micropores ( V micro = 0.28 cm 3 /g) can uptake H 2 gas as high as 2.17 wt % at 77 K/1 bar.…”

Hydrogen (H2) is one of the best candidates to replace current petroleum energy resources due to its rich abundance and clean combustion. However, the storage of H2 presents a major challenge. There are two methods for storing H2 fuel, chemical and physical, both of which have some advantages and disadvantages. In physical storage, highly porous organic polymers are of particular interest, since they are low cost, easy to scale up, metal-free, and environmentally friendly. In this review, highly porous polymers for H2 fuel storage are examined from five perspectives: (a) brief comparison of H2 storage in highly porous polymers and other storage media; (b) theoretical considerations of the physical storage of H2 molecules in porous polymers; (c) H2 storage in different classes of highly porous organic polymers; (d) characterization of microporosity in these polymers; and (e) future developments for highly porous organic polymers for H2 fuel storage. These topics will provide an introductory overview of highly porous organic polymers in H2 fuel storage.

“…Jiang et al [31] used a carbazole derivative, triindolocarbazole (TCB), to synthesize a TCB-CMP that exhibits blue luminescence and could be used to detect arenes upon exposure to their vapors. Thereafter, the CMP family has been largely developed and utilized in a plethora of fields including light emitters, [32] energy storage, [33,34] catalysis, [35] gas storage/separations, [36] chemosensors, [37,38] energy conversion, [39,40] biological applications, [41] etc.…”

covalently bonded organic moieties. Because of their unique properties derived from their tunable porous structures and the multiple functional groups, which can be included in their backbones, POPs have been actively investigated for multiple applications including gas storage/separation, [2,3] catalysis, [4][5][6] optoelectronics, [7,8] sensing, [9][10][11] energy storage, and conversion. [12,13] Aside from their high specific surface areas, they furthermore show excellent chemical stability, light-weight and a versatile chemistry for modification and functionalization. POPs can be further classified into two categories based on their crystallinity. Crystalline POPs are usually summarized under the name covalent organic frameworks [14][15][16] (COFs). Amorphous POPs are further divided, based on their structure or construction principles into hyper-crosslinked polymers [17,18] (HCPs), polymers of intrinsic microporosity [19,20] (PIMs), porous aromatic frameworks [21,22] (PAFs), and others. Recent research has seen increasing interest on amorphous POPs, especially when their skeleton is π-conjugated. In these highly porous networks, π-conjugation is superimposed with meso-/microporosities, i.e., electron transport in the polymer backbone is accompanied by mass transport in the porous system, which enable many intriguing properties and applications, e.g., in energy storage and conversion, [23,24] or optoelectronics. [25,26] As such, the importance of π-conjugation in porous polymer networks has defined another emerging functional POP class-the conjugated microporous polymers (CMPs). As mentioned, such CMPs [27] are a unique class of POPs exhibiting extended π-conjugated structures and permanent nanopores (Table S1). Earlier, McKeown et al. [28] discussed an important concept of preparing robust nanoporous materials by the covalent binding of planar molecules via a rigid spirocyclic linker. In 2007, Cooper et al. [29] reported a highly cross-linked, microporous poly(arylene ethynylene)s network, thus the first microporous polymer network with distinct π-conjugation and introduced the term "conjugated microporous polymer (CMP)" for this class of materials. Since their discovery, CMPs chemistry has intrigued scientists across the globe and been promoted rapidly, resulting in a strong growth in publications over the last decade. For instance, Thomas et al. [30] reported a spirobifluorene-type CMP with stable interface and application potential in organic light emitting diodes Since discovered in 2007, conjugated microporous polymers (CMPs) have been developed for numerous applications including gas adsorption, sensing, organic and photoredox catalysis, energy storage, etc. While featuring abundant micropores, the structural rigidity derived from CMPs' stable π-conjugated skeleton leads to insolubility and thus poor processability, which severely limits their applicability, e.g., in CMP-based devices. Hence, the development of CMPs whose structure can not only be controlled on the micro-but also on the macroscale have...

“…Moreover, CMPs offer advantages over several other POPs such as fine‐tuned microporosity, prominent physico‐chemical properties, good stability and high specific surface area. They have emerged as promising useful materials in electrodes, gas sorption and storage, catalysis, light harvesting, superhydrophobic separation and antibacterial applications . CMPs also have been used as efficient adsorbents for ions, dye and iodine …”

BACKGROUND A magnetic conjugated microporous polymer (MCMP) composite was designed with bromo groups of CMP and amino groups on the surface of Fe3O4 nanoparticles that acted as promising adsorbents for wastewater treatment. Fe3O4 nanoparticles were successfully bonded on the predesigned CMP material to form the MCMP by means of a new and simple nucleophilic substitution reaction in organic media. RESULTS The MCMP could be separated by applying an external magnetic field because of the Fe3O4 nanoparticles. It exhibited sufficient dye adsorption for methylene blue (MB) with a high sorption capability of 869.43 mg g−1 in aqueous solutions. The recovery and reusability of MCMP were >70% after six cycles of desorption and regeneration, indicating that the MCMP had excellent cycle stability. The magnetization saturation strength of MCMP was 13.5 emu g−1 which was sufficient to be magnetically separated from wastewater using artificial magnetic fields. CONCLUSION The MCMP possessed excellent adsorption capacity and dispersibility, and good recyclability after banded with functionalized Fe3O4 nanoparticles. The excellent properties of MCMP indicated that it could be used as an adsorbent with great application potential for quick separation of water pollutants such as dyes in wastewater treatment. © 2019 Society of Chemical Industry
