“…In addition, we have previously prepared a series of CMPs through Sonogashira–Hagihara cross-couplings of a tetrabenzonaphthalene (TBN) monomer with tetraphenylethylene (TPE), pyrene (Py), and carbazole (Car) units; we then mixed them with highly conductive single-walled carbon nanotubes (SWCNTs) to improve their conductivity [ 45 ], with the TBN-Py-CMP/SWCNT composite exhibiting high capacitance (430 F g –1 ) at a current density of 0.5 A g –1 because of strong π-stacking of the SWCNTs with the CMPs [ 45 ]. In addition, we have previously prepared two-hybrid porous POSS-F-POIP and POSS-A-POIP materials through Heck reactions of octavinylsilsesquioxane (OVS) with brominated fluorene (F–Br 2 ) and anthraquinone (A-Br 2 ) derivatives, respectively [ 47 ]. These POSS-A-POIP and POSS-F-POIP materials exhibited specific capacitances of 152.5 and 36.2 F g –1 , respectively, at 0.5 A g –1 .…”

“…These POSS-A-POIP and POSS-F-POIP materials exhibited specific capacitances of 152.5 and 36.2 F g –1 , respectively, at 0.5 A g –1 . The higher capacitance of POSS-A-POIP was due to the faradaic reaction of anthraquinone and the π-conjugated system [ 47 ]. Shao et al [ 76 ] prepared N-doped Cobalt@graphitized carbon material (ZC600) derived from ZIF-67 assisted polyvinylidene fluoride hollow fiber membrane by a simple anaerobic calcination method at a relative low temperature (600 °C).…”

“…Thus, extensive research efforts will be needed to develop novel materials possessing high specific surface areas that can increase the energy density of supercapacitors while maintaining their power density and cycling stability. In this regard, many porous organic polymers (POPs) featuring suitable pore size distributions—including covalent triazine frameworks (CTFs) [ 39 ], covalent organic frameworks (COFs) [ 40 , 41 , 42 ], hypercrosslinked porous polymers (HCPs) [ 43 , 44 ], conjugated microporous polymers (CMPs) [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ], metal–organic framework [ 48 , 49 , 50 ], and ferrocene-based conjugated microporous polymers [ 51 ]—have been developed to improve the performance of supercapacitors. Supercapacitors can store energy through faradaic (pseudocapacitance) and non-faradaic [electric double-layer capacitance (EDLC)] processes [ 43 , 44 , 45 , 46 , 47 ].…”

There is currently a pursuit of synthetic approaches for designing porous carbon materials with selective CO2 capture and/or excellent energy storage performance that significantly impacts the environment and the sustainable development of circular economy. In this study we prepared a new bio-based benzoxazine (AP-BZ) in high yield through Mannich condensation of apigenin, a naturally occurring phenol, with 4-bromoaniline and paraformaldehyde. We then prepared a PA-BZ porous organic polymer (POP) through Sonogashira coupling of AP-BZ with 1,3,6,8-tetraethynylpyrene (P-T) in the presence of Pd(PPh3)4. In situ Fourier transform infrared spectroscopy and differential scanning calorimetry revealed details of the thermal polymerization of the oxazine rings in the AP-BZ monomer and in the PA-BZ POP. Next, we prepared a microporous carbon/metal composite (PCMC) in three steps: Sonogashira coupling of AP-BZ with P-T in the presence of a zeolitic imidazolate framework (ZIF-67) as a directing hard template, affording a PA-BZ POP/ZIF-67 composite; etching in acetic acid; and pyrolysis of the resulting PA-BZ POP/metal composite at 500 °C. Powder X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, transmission electron microscopy, and Brunauer–Emmett–Teller (BET) measurements revealed the properties of the as-prepared PCMC. The PCMC material exhibited outstanding thermal stability (Td10 = 660 °C and char yield = 75 wt%), a high BET surface area (1110 m2 g–1), high CO2 adsorption (5.40 mmol g–1 at 273 K), excellent capacitance (735 F g–1), and a capacitance retention of up to 95% after 2000 galvanostatic charge–discharge (GCD) cycles; these characteristics were excellent when compared with those of the corresponding microporous carbon (MPC) prepared through pyrolysis of the PA-BZ POP precursors with a ZIF-67 template at 500 °C.

The robust fully conjugated covalent organic frameworks (COFs) are emerging as a novel type of semi‐conductive COFs for optoelectronic and energy devices due to their controllable architectures and easily tunable the highest occupied molecular orbital (HOMO) and the lowest occupied molecular orbital (LUMO) levels. However, the carrier mobility of such materials is still beyond requirements due to limited π‐conjugation. In this study, a series of new polyarylether‐based COFs are rationally synthesized via a direct reaction between hexadecafluorophthalocyanine (electron acceptor) and octahydroxyphthalocyanine (electron donor). These COFs have typical crystalline layered structures, narrow band gaps as low as ≈0.65 eV and ultra‐low resistance (1.31 × 10−6 S cm−1). Such COFs can be composed of two different metal‐sites and contribute improved carrier mobility via layer‐altered staking mode according to density functional theory calculation. Due to the narrow pore size of 1.4 nm and promising conductivity, such COFs and electrochemically exfoliated graphene based free‐standing films are fabricated for in‐plane micro‐supercapacitors, which demonstrate excellent volumetric capacitances (28.1 F cm−3) and excellent stability of 10 000 charge–discharge cycling in acidic electrolyte. This study provides a new approach toward dioxin‐linked COFs with donor‐acceptor structure and easily tunable energy levels for versatile energy storage and optoelectronic devices.

Low dielectric constant (k) polymers with excellent comprehensive properties are useful materials in the microelectronics industry as matrix resins or encapsulation layers. With the inherent low polarization, high reactivity, good processability, and low cost, poly(dicyclopentadiene) (PDCPD) has received considerable attention as low‐k materials. However, its practical application is limited by the relatively high thermal expansion and k value. Herein, three norbornene‐functionalized polyhedral oligomeric silsesquioxanes (POSSs) with T8, T10, and T12 polyhedral cores are synthesized and employed for enhancing the dielectric and comprehensive properties of PDCPD via reactive blending. The results show that these POSSs have good compatibility with PDCPD matrix and nano‐dispersed POSSs particles could be obtained. As a result, the materials’ properties can be largely enhanced by varying the POSS content and POSS size. Especially, PT12N12‐40 (40 wt% of T12N12) shows the lowest k value (2.1) and coefficient of thermal expansion (63.4 ppm°C−1), highest glass transition temperature (202.5 °C), yield strength (78.0 MPa), and elastic modulus (2.36 GPa), along with excellent hydrophobicity. This study highlights a useful strategy to fabricate high‐performance low‐k polymer nanocomposites by using larger POSS and reactive blending, which provides useful materials for the future microelectronic industry and high frequency communication.
