“…We recorded the CV profiles of the POSS-OXD, POSS-Th, and POSS-TPTh POIPs at various scan rates between 1.00 to 0 V ( Figure 7 a–c). The rectangular CV profiles with slight humps for all three POSS systems indicate that their capacitive effects were caused by EDLC [ 76 , 77 ]. The humps suggest the involvement of pseudocapacitance responses emerging from the presence of the N and S heteroatoms and electron-rich phenyl groups in the OXD, Th, and TPTh structures, respectively, facilitating the passage of the electrolyte to the electrode area and for the electrons to keep moving from one electrode to another [ 78 , 79 ].…”

In this study, we synthesized three hybrid microporous polymers through Heck couplings of octavinylsilsesquioxane (OVS) with 2,5-bis(4-bromophenyl)-1,3,4-oxadiazole (OXD-Br2), tetrabromothiophene (Th-Br4), and 2,5-bis(4-bromophenyl)-3,4-diphenylthiophene (TPTh-Br2), obtaining the porous organic–inorganic polymers (POIPs) POSS-OXD, POSS-Th, and POSS-TPTh, respectively. Fourier transform infrared spectroscopy and solid state 13C and 29Si NMR spectroscopy confirmed their chemical structures. Thermogravimetric analysis revealed that, among these three systems, the POSS-Th POIP possessed the highest thermal stability (T5: 586 °C; T10: 785 °C; char yield: 90 wt%), presumably because of a strongly crosslinked network formed between its OVS and Th moieties. Furthermore, the specific capacity of the POSS-TPTh POIP (354 F g−1) at 0.5 A g−1 was higher than those of the POSS-Th (213 F g−1) and POSS-OXD (119 F g−1) POIPs. We attribute the superior electrochemical properties of the POSS-TPTh POIP to its high surface area and the presence of electron-rich phenyl groups within its structure.

“…[24] Figure 3D presents the specific capacitance calculated from the GCD curves, indicating a maximal specific capacitance of 145 F g −1 at 1 A g −1 , superior than many previously reported quinone-based supercapacitors. [2,3,25] The gradual decrease of the specific capacitance in higher currents (20% capacitance retention at 10 A g −1 ) is also indicative of a considerable pseudo-capacitance contribution. The cycling experiment in Figure 3E reveals high capacitance retention of around 80% after 5000 cycles, and the Nyquist plot in Figure 3F further underlies low series resistance (≈0.7 Ω) and charge transfer resistance (≈5.5 Ω), that are better compared to various reported organic supercapacitors.…”

“…Specifically, the device generated a high energy density of 36.2 Wh kg −1 at a power of 995 W kg −1 which is superior compared to many reported systems. [2,3,18,25,32] The pronounced energy and power densities accomplished in the bis-APDA/PANI-PPy/rGO device in both aqueous and nonaqueous ionic liquid electrolytes reflect the combined contributions of bis-APDA and PANI, providing high charge storage capacity and fast discharge. The excellent electrochemical properties of the electrode reflect both the redox reactions in the anthraquinone in Bis-APDA and the EDLC contributions of the polydiacetylene network, combined with the efficient electron transport properties of PANI.…”

Organic supercapacitors are considered attractive alternatives to traditional inorganic‐based charge storage devices due to their synthetic versatility, low cost, and environment‐friendliness features. Photopolymerized anthraquinone‐polydiacetylene is employed as a core component in high‐performance asymmetric supercapacitors (ASCs). Specifically, interspersed polydiacetylene‐anthraquinone/polyaniline (PANI) electrodes are prepared via drop‐casting and used as cathodes in devices employing polypyrrole/reduced graphene oxide anodes using aqueous or ionic liquid electrolytes. The excellent electrochemical properties of the polydiacetylene‐anthraquinone/PANI electrodes, specifically high capacitance (specific capacitance ≈720 F g−1 at 1 A g−1), long discharge time, and cycling stability, are ascribed to the superior redox profile of the anthraquinone and ambipolar charge transport associated with the polydiacetylene framework. The asymmetric supercapacitor prepared using the polydiacetylene‐anthraquinone/PANI electrodes displays a high energy density of 36 Wh kg−1 at a power density of 995 W kg−1, underscoring possible utilization of the anthraquinone‐polydiacetylene derivative in practical energy storage devices.

“…The ELDC of the materials can be attributed to their surface areas. The materials that have high surface areas, such as carbonaceous materials, conjugated microporous polymers (CMPs), and covalent organic frameworks (COFs), usually have high EDLC [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. It is, therefore, important to explore new electrode materials that synergize both EDLC and PC.…”

In recent years, conjugated microporous polymers (CMPs) have become important precursors for environmental and energy applications, compared with inorganic electrode materials, due to their ease of preparation, facile charge storage process, π-conjugated structures, relatively high thermal and chemical stability, abundance in nature, and high surface areas. Therefore, in this study, we designed and prepared new benzobisthiadiazole (BBT)-linked CMPs (BBT–CMPs) using a simple Sonogashira couplings reaction by reaction of 4,8-dibromobenzo(1,2-c;4,5-c′)bis(1,2,5)thiadiazole (BBT–Br2) with ethynyl derivatives of triphenylamine (TPA-T), pyrene (Py-T), and tetraphenylethene (TPE-T), respectively, to afford TPA–BBT–CMP, Py–BBT–CMP, and TPE–BBT–CMP. The chemical structure and properties of BBT–CMPs such as surface areas, pore size, surface morphologies, and thermal stability using different measurements were discussed in detail. Among the studied BBT–CMPs, we revealed that TPE–BBT–CMP displayed high degradation temperature, up to 340 °C, with high char yield and regular, aggregated sphere based on thermogravimetric analysis (TGA) and scanning electron microscopy (SEM), respectively. Furthermore, the Py–BBT–CMP as organic electrode showed an outstanding specific capacitance of 228 F g–1 and superior capacitance stability of 93.2% (over 2000 cycles). Based on theoretical results, an important role of BBT–CMPs, due to their electronic structure, was revealed to be enhancing the charge storage. Furthermore, all three CMP polymers featured a high conjugation system, leading to improved electron conduction and small bandgaps.
