Synthesis and design of hypercrosslinked porous organic frameworks containing tetraphenylpyrazine unit for high‐performance supercapacitor

Abstract: Human society faces significant environmental challenges due to the rapid production and consumption of fossil fuels. Therefore, developing effective and environmentally friendly methods of generating and storing energy is essential. Hypercrosslinked polymers (HPPs) have become increasingly popular due to their diverse preparation methods, simple functionalization, large specific surface area, low cost, mild reaction conditions, high chemical and thermal stability, and small size. We synthesized two hypercross… Show more

“…These values indicate that the An-Ph-TPA CMP framework has slightly higher capacitive retention than the An-Ph-Py CMP framework. Furthermore, specific capacitances of An-Ph-TPA CMP (116 F g −1 ) and An-Ph-Py CMP (83 F g −1 ) are higher than TPA-Bz CMP (55.1 F g −1 ) [71], Pyra-BP-HPP (94 F g −1 ) [71], Py-BSU CMP (38 F g −1 ) [72], TBN-BSU CMP (70 F g −1 ) [72], TBN-TPE-CMP (18.45 F g −1 ) [73], TBN-Car-CMP (18.90 F g −1 ) [73], TBN-Py-CMP (31 F g −1 ) [73], and CoPc-CMP(13.7 F g −1 ) [36]. The Ragone plot comparison between An-Ph-TPA and An-Ph-Py CMP frameworks reveals that the former exhibits a maximum energy density of 16 W h kg −1 , which is twice as high as that of the latter, which is only 12 W h kg −1 when the power density is 500 kW kg −1 , as shown in Figure 7c.…”

“…These GCD curves exhibited triangular shapes with slight bends, which indicated EDLC and pseudocapacitive characteristics. [58][59][60][61] The specific capacitance of the CE-Py POP/SWCNT nanocomposite was calculated as 189 F g −1 at 1 A g −1 [Fig. 6(c)].…”

“…Investigating reasonable and cost-effective methods of energy collection and storage is therefore important. Due to their excellent qualities including high energy densities, quick charge/discharge rates, and extended lifespan, supercapacitors (SCs) have received a lot of interest in this respect [1][2][3]. SCs are appropriate for a variety of applications, including biological defibrillators and wind turbines, thanks to their advantageous characteristics [4][5][6].…”
