“…A dispersion of 100 μg/mL was found to completely inhibit the bacterial activity in 2 h. This is one of the first examples based on acetylenic materials. On the other hand, Choi and coworkers 930 reported an OPE-based wettable and compressible polymer that can remove both methylene blue and methylene orange dyes. However, due to the presence of carboxylate functionality over the polymeric chain, cationic dye was found to be adsorbed preferentially over the anionic ones.…”

“…52 As well as Chang et al prepared a compressible CMP sponge composite (PUS-MOP-A) by in situ polymerization of carboxyl-containing 2,5-diiodobenzoic acid, 1,3,5-triethynyl benzene, and 1,4-diiodobenzene on a block and compressible polyurethane sponge (Figure 7a). 53 The porous composites were transformed from superhydrophobic to superhydrophilic by KOH treatment, 53 which could provide more accessible catalytic active sites for photocatalysis. Furthermore, Chang et al used the PVA-silica nanofiber (PVASi) obtained from poly(vinyl alcohol) (PVA) and tetraethyl orthosilicate (TEOS) as a substrate to prepare a compressible CMP-based foam with core−shell structure by an in situ Sonogashira−Hagihara reaction of 2,5-dibromoaniline with 1,3,5-triethynylbenzene (Figure 7b).…”

Conjugated microporous polymers (CMPs) as a new type of conjugated polymers have attracted extensive attention in academia and industry because of the combination of microporous structure and π-electron conjugated structure. The construction and application of gels and monoliths based on CMPs constitute a fertile area of research, promising to provide solutions to complex environmental and energy issues. This review summarizes and objectively analyzes the latest advances in the construction and application of processable CMP gels and monoliths, linking the basic and enhanced properties to widespread applications. In this review, we open with a summary of the construction methods used to build CMP gels and monoliths and assess the feasibility of different preparation techniques and the advantages of the products. The CMP gels and monoliths with enhanced properties involving various special applications are then deliberated by highlighting relevant scientific literature and discussions. Finally, we present the issues and future of openness in the field, as well as come up with the major challenges hindering further development, to guide researchers in this field.

“…Chang et al [ 189 ] prepared a compressible multilayer CMP composite via Sonogashira–Hagihara coupling reaction of 1,3,5‐triethynyl benzene, 1,4‐diiodobenzene and 2,5‐diiodobenzoic acid inside a polyurethane sponge. The CMP formed inside the polyurethane sponge network demonstrated a fiber‐shaped morphology and can be deprotonated to a carboxylate polymer with KOH.…”

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...
