“…with the electrolyte. [59][60][61][62][63] The current densities increased upon increasing the scan rate without altering the morphologies of the CV curves, validating the high-rate capabilities, stabilities, and kinetic properties of the TPA-DHTP-BZ POP before and after ROP. Furthermore, we examined the charge/discharge trends and capacitances of these compounds at various current densities [Fig.…”

“…Additionally, the compounds’ capacitance and GCD curves were investigated at current densities from 0.5 to 20 A g –1 (Figure c–f). The GCD curves displayed a triangular shape with a slight bend, indicating both EDLC and pseudo-capacitive characteristics. − All compounds’ discharge times were longer than their charging times, which suggest greater capacitance . Higher capacitance was achieved at low scan rates because slower scan rates allow ions in the electrolyte sufficient time to reach and interact with all the active sites present in the charged materials.…”

We successfully synthesized three perylene dianhydride (PDI)-based conjugated microporous polymers (CMPs), namely, Py-Ph-Pery, TPE-Ph-Pery, and TPA-Ph-Pery CMPs, through a Suzuki−Miyaura coupling reaction. The precursors used in the reaction contained brominated compounds of pyrene (Py), tetraphenylethylene (TPE), triphenylamine (TPA), and 1,4benzeneboronic acid, which were coupled with redox-active PDI unit. To evaluate the thermal stability, molecular structure, and porosity properties of the synthesized CMPs, we conducted an examination of their Brunauer−Emmett−Teller isotherm, along with spectroscopic and microscopic analyses. These CMPs demonstrated moderate thermal stability based on thermogravimetric analysis. In terms of electrochemical performance, the Py-Ph-Pery CMP exhibited a high capacitance of 300 F g −1 (measured at 0.5 A g −1 ), indicating its excellent capacitive properties. Furthermore, the Py-Ph-Pery CMP displayed exceptional cycle stability at 10 A g −1 , retaining more than 93% of its capacity over 5000 cycles. The findings illustrate the potential of these CMPs for reliable and durable energy storage applications. Additionally, we utilized synthesized CMPs to assess the electrochemical characteristics of a symmetric coin supercapacitor. The results further validate the suitability of these CMPs for practical electrical energy storage applications, highlighting their significant promise.

“…Therefore, TBN-BSU CMP is a better choice for energy storage applications. Due to its high surface area, structural integrity, and compatibility with bis-sulfone units, TBN-BSU CMP exhibited this behavior [83][84][85][86][87][88]. In Figures 7 and S32, the EIS results indicated that Py-BSU CMP and TBN-BSU CMP have slightly different Nyquist curves, suggesting they have different resistances.…”

We have successfully synthesized two types of two-dimensional conjugated microporous polymers (CMPs), Py-BSU and TBN-BSU CMPs, by using the Sonogashira cross-coupling reaction of BSU-Br2 (2,8-Dibromothianthrene-5,5′,10,10′-Tetraoxide) with Py-T (1,3,6,8-Tetraethynylpyrene) and TBN-T (2,7,10,15-Tetraethynyldibenzo[g,p]chrysene), respectively. We characterized the chemical structure, morphology, physical properties, and potential applications of these materials using various analytical instruments. Both Py-BSU and TBN-BSU CMPs showed high thermal stability with thermal decomposition temperatures (Td10) up to 371 °C and char yields close to 48 wt%, as determined by thermogravimetric analysis (TGA). TBN-BSU CMPs exhibited a higher specific surface area and porosity of 391 m2 g−1 and 0.30 cm3 g−1, respectively, due to their large micropore and mesopore structure. These CMPs with extended π-conjugated frameworks and high surface areas are promising organic electroactive materials that can be used as electrode materials for supercapacitors (SCs) and gas adsorption. Our experimental results demonstrated that the TBN-BSU CMP electrode had better electrochemical characteristics with a longer discharge time course and a specific capacitance of 70 F g−1. Additionally, the electrode exhibited an excellent capacitance retention rate of 99.9% in the 2000-cycle stability test. The CO2 uptake capacity of TBN-BSU CMP and Py-BSU CMP were 1.60 and 1.45 mmol g−1, respectively, at 298 K and 1 bar. These results indicate that the BSU-based CMPs synthesized in this study have potential applications in electrical testing and CO2 capture.
