Two pyrene-functionalized CTFs through ionothermal treatment TCNPy in the presence of molten zinc chloride at 500 °C, which displayed high-performance CO2 uptake and supercapacitance.

Designed azo-linked conjugated microporous polymers for CO2 uptake and removal applications

“…Noticeably, the CO 2 uptake efficacy of our tested CMPs are among the highest reported Azo-linked CMPs [ 69 – 71 ]. In addition, they represented a significant CO 2 adsorption capacity relative to other porous substances [ 27 , 68 , 72 ]. Moreover, the isosteric heats of adsorption ( Q st ) of these azo-based CMPs were calculated from their CO 2 adsorption at 298 K and 273 K, by the aid of Clausius–Clapeyron equation as shown in Fig.…”

Multifunctional Polyhedral Oligomeric Silsesquioxane (POSS) Based Hybrid Porous Materials for CO2 Uptake and Iodine Adsorption

“…The preparation of porous organic polymers (POPs) has become a hot topic in the academic and industry fields due to their interesting features, such as high physicochemical stability, porous character, low density, facile preparation, low regeneration energy, and good thermal and chemical stabilities [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Porous organic polymers have been applied in different applications such as light harvesting, chemical sensors, catalysis, iodine uptake, H 2 production from water, water treatment, optoelectronic devices, carbon dioxide reduction, nanofiltration, enantioseparation, energy storage, gas separation, and adsorption [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. The synthesis of POPs was successfully achieved using various synthetic methods, including Friedel–Crafts arylation, Schiff base reactions, Suzuki reactions, Yamamoto reactions, Heck reactions, and Sonogashira reactions [ 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ].…”

Meso/Microporous Carbons from Conjugated Hyper-Crosslinked Polymers Based on Tetraphenylethene for High-Performance CO2 Capture and Supercapacitor

“…Ultra-capacitors or electric double layer capacitors (also called supercapacitors) are energy storage devices that possess long cycle life, low maintenance, low internal resistance, light weight, delivering high energy and high efficiency, high power, flexible packaging, light weight and maintenance, and a wide range of temperature compared with other energy devices such as batteries [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. Based on the supercapacitors mechanism for energy storage, supercapacitors can be divided into electrical double layer capacitor (EDLC), hybrid capacitor, and finally pseudocapacitor [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ]. Hyper-crosslinked polymers (HCPs) [ 28 , 29 , 30 , 31 , 32 , 33 ], covalent organic frameworks (COF) [ 34 , 35 , 36 , 37 , 38 , 39 , 40 ], conjugated microporous polymers (CMPs) [ 41 , 42 , 43 , 44 , 45 ], and polymers of intrinsic microporosity (PIMs) are considered as types of microporous organic polymers (MOPs) [ 46 , 47 , 48 , 49 ].…”
