Construction of Ultrastable Conjugated Microporous Polymers Containing Thiophene and Fluorene for Metal Ion Sensing and Energy Storage

Abstract: In this study, we have used the one-pot polycondensation method to prepare novel 2D conjugated microporous polymers (Th-F-CMP) containing thiophene (Th) and fluorene (Fl) moieties through the Suzuki cross-coupling reaction. The thermogravimetric analysis (TGA) data revealed that Th-F-CMP (Td10 = 418 °C, char yield: 53 wt%). Based on BET analyses, the Th-F-CMP sample displayed a BET specific surface area of 30 m2 g−1, and the pore size was 2.61 nm. Next, to show the effectiveness of our study, we utilized Th-F-… Show more

“…The knee frequencies for the Try-Ph-Th, Try-Ph-Py, and Try-Ph-TPE CMPs were 93.42, 17.29, and 127.5 Hz, respectively. Thus, the knee frequency of the Try-Ph-TPE CMP was higher than those of the other electrodes, suggesting its extraordinary performance when employed as an electrode material in energy storage applications. …”

“…Figure c displays the frequency-dependent magnitude Bode plots, revealing lines with negative slope in the low-frequency region, along with modest resistance in the higher-frequency region. From this information, we predicted extraordinary capacitive behavior for all three of these porous materials when used as electrode materials for energy application. …”

“…Supercapacitors (SCs) are regarded as an alternative technology to fuel cells, the usual capacitor, and batteries. They acquired widespread interest compared with other batteries and conventional capacitors due to their lower environmental impact, prolonged cycle life, and higher power capability [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. SCs have two common types: electrode–electrolyte interfaces in electric double-layer capacitors (EDLCs), which are followed by physical adsorption; and pseudocapacitors, which involve faradaic interactions that occur between the electrolyte and organic moieties or active metal oxides [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ].…”

“…They have recently gained popularity in the field of porous materials because of their low density, high porosity, and excellent thermal stability [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. POPs have found applications in, for example, energy storage, lithium-ion batteries, gas separation, nanofiltration, drug carrying, optoelectronics, photocatalysis, and water treatment [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. They have been synthesized using various techniques, including Friedel–Crafts, Yamamoto, Schiff base, Sonogashira, Yamamoto, Heck, and Suzuki reactions [ 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ].…”
