“…Another promising strategy is to design porous polymeric frameworks with conducting properties as electrode materials for supercapacitors. The conductive frameworks enable the high utilization of the large surface area for electrical double layer capacitance and heteroatom effect (N) for pseudocapacitance, as has been found in aza‐fused CMPs (Figure g), triazatruxene‐based microporous polymers (Figure h), and triazine‐based porous frameworks (Figure i) …”

have triggered serious threats to the survival and development of mankind. Consequently, exploring novel materials with task-specific applications is of fundamental importance for the sustainable development of economy and society. The burgeoning progress of nanomaterials in recent years has demonstrated that porosity is one of the essential factors in determining material properties for possible breakthroughs in their applications. Therefore, porous materials are playing important roles in many well-established applications and emerging technologies for challenging social and economic issues due to their intrinsic characteristics of large surface areas, open channels, and the possible control over the pore environment. According to International Union of Pure and Applied Chemistry, the pores of porous materials are classified into three categories by their pore sizes: micropores are smaller than 2 nm, mesopores are in the range of 2-50 nm, and macropores are larger than 50 nm. [1] Their pore walls include the organic skeleton (e.g., porous polymers, organic porous cages, and supramolecular organic frameworks), the inorganic skeleton (e.g., zeolites, porous carbons, and mesoporous silica), and the hybrid skeleton (e.g., metal-organic frameworks (MOFs)).Among the developed porous materials, porous polymers have attracted an increasing level of research interest owing to their potential to integrate the advantages of both porous materials and polymers. [2,3] Table 1 lists the characteristic structural features and properties of porous polymers, and gives a systematic comparison to other typical porous materials, such as zeolites, porous carbons, and MOFs. Porous polymers, zeolites, porous carbons, and MOFs share a number of features such as high permanent porosities, large surface areas, and designable pores and voids. However, they are different in several important aspects. The major advantages of porous polymers over many other porous materials are their chemical diversity and easy processability. Compared to zeolites and porous carbons, the synthesis of porous polymers is generally more versatile and can be approached in a way that conforms to the concept of rational materials design. Similar to MOFs, porous polymers inherit the excellent chemical and physical tunability afforded by the versatility of organic chemistry. Furthermore, Exploring advanced porous materials is of critical importance in the development of science and technology. Porous polymers, being famous for their all-organic components, tailored pore structures, and adjustable chemical components, have attracted an increasing level of research interest in a large number of applications, including gas adsorption/storage, separation, catalysis, environmental remediation, energy, optoelectronics, and health. Recent years have witnessed tremendous research breakthroughs in these fields thanks to the unique pore structures and versatile skeletons of porous polymers. Here, recent milestones in the diverse applications of porous polymers are presented, ...

“…As shown in the C1s core-level XPS spectra ( Figure S5a,c), PCMPs exhibited two peaks at~284.7 and~285.1 eV attributed to aryl C=C and C=N bonds; an additional peak at~287.5 eV assigned to C=O bonds of acetyl groups, respectively. [22,23] The N1s core-level XPS spectra of PCMPs ( Figure S5b,d) displayed the two peaks at~398.5 eV owing to pyridinic N. [15,22] All the information signifies that the desired structures of PCMPs are actually presented as suggested in Figure 1. Note that, replacing acetic acid with pyridine, asprepared PCMPs showed close wavenumber and chemical shift values ( Figure S4a Articles 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 tures.…”

Efficient materials for electrochemical energy storage have received much attention. Herein we report a green metal‐free route to synthesize pyridyl conjugated microporous polymers (PCMPs) as precursors for nitrogen‐doped porous carbon microspheres (NCMs) with high surface areas up to 1232 m2 g−1 via a simple carbonization method. The resulting NCMs as supercapacitor electrodes exhibit high specific capacitance of 324 F g−1 at a current density of 0.1 A g−1, and high rate ability (182 F g−1 at 10 A g−1), and excellent cyclability (remained >97 % of initial capacitance at 2 A g−1 after 10000 cycles). This work also presents that molecular engineering of PCMP precursor, pyrolysis temperature and charge/discharge cycling allow the electrochemical energy storage properties of the NCMs to be controlled.

Metal-organic frameworks (MOFs), a new class of crystalline porous materials, can be applied in many fields as adsorbents, supercapacitors, catalysts, and so on because of, among others, their superior properties of large surface area, tunable pore size, diverse structures. However, the low stability and selectivity of traditional MOFs indicate that they are not the best configuration for the applications outlined above. In this case, a type of composite made from an assembly of graphene-based materials and MOFs that exhibits the advantages of the parent materials has attracted widespread attention in recent years. This review provides an overview of the recent developments of MOF/graphene-based materials, focusing on their applications in gas separation/storage, water purification, chemical sensors, batteries, supercapacitors, and catalysts, as well as their preparation methods.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adfm.201804950. traditional method, they can be excellent alternatives of single MOFs to overcome the above-mentioned difficulties. [34][35][36][37][38] Graphene-based materials have recently introduced new possible applications because of their unique structure and low toxicity, as well as their excellent electronic, thermal, electrochemical, and mechanical properties. [39] More recently, many reports have confirmed that the introduction of graphene-based materials into other materials can lead to surprising improvements in electronic conductivity and stability. [38,40] Under these circumstances, it is reasonable to consider whether composites made from the assembly of graphene-based materials and MOFs possess extraordinary characteristics given that the parent materials have complementary properties. [40][41][42] Naturally, the idea of hybridizing graphene derivatives with MOFs materialized and soon attracted widespread attention. [43][44][45] According to recent research, composites of MOF/graphene-based materials can integrate the advantages and mitigate the shortcomings of the individual components perfectly, enabling the composites to possess improved stability, enhanced electrical conductivity, high selectivity, and template effects. [34,[46][47][48][49] With the combination of MOF and graphene-based materials, the unexpected interactions take place and bring unique performance in many applications. Thanks to the ionic groups and the aromatic sp 2 domains, graphene-based materials can not only function as structural nodes, but also participate in bonding interactions, which would be more active in MOFs. What's more, carboxylate and pyridine groups of graphene-based materials play important part in the assemble, which could enhance the coordination bonding and guide the growth of MOF, providing a more beneficial structure. These special interactions are unique in MOF/graphenebased materials, which indicates that this kind of materials deserve more attention. As concluded in Scheme 1, the addition of graphene-based material...
