The rising CO2 concentration in the atmosphere contributes significantly to global warming, necessitating effective carbon capture techniques. Amine-based solvents are widely employed for chemisorption of CO2, although they have drawbacks, such as degradation, corrosion, and high regeneration energy requirements. Physical adsorption utilizing microporous adsorbents is a viable alternative that offers excellent efficiency selectivity capture. This work presents facile one-pot synthesis 3D-triptycene-containing hyper-cross-linked polymer (TBPP-OH) possessing hydroxyl groups. presence triptycene units TBPP-OH polymeric structure gives several desirable features, inherent microporosity, larger surface area, improved thermal stability. showed considerable microporosity (%Vmic = 70%), BET-specific area (SABET) 838 m2 g–1, good stability (Td 372 °C char yield > 60%) which makes it promising adsorbent A strong affinity was shown by with Qst 32.9 kJ/mol demonstrating superior capacity 2.77 mmol/g at 273 K 1 bar pressure where volume micropore plays significant role. values over N2 CH4 were also estimated be reasonably indicating potential separation different applications. mechanism investigated using Langmuir dual-site models.

Conjugated microporous polymers (CMPs) feature extended excellent porosity properties and fully conjugated electronic systems, making them highly effective for several uses, including photocatalysis, dye adsorption, CO2 capture, supercapacitors, so on. These are known their high specific surface area adjustable porosity. To synthesize DHTP-CMPs (specifically TPE-DHTP CMP Anthra-DHTP CMP) with abundant nitrogen (N) oxygen (O) adsorption sites spherical structures, we employed a straightforward Schiff-base [4 + 2] condensation reaction. This involved using 2,5-dihydroxyterephthalaldehyde (DHTP-2CHO) as the primary building block phenolic OH group source, along two distinct structures: 4,4′,4″,4"'-(ethene-1,1,2,2-tetrayl)tetraaniline (TPE-4NH2) 4,4′,4″,4"'-(anthracene-9,10-diylidenebis(methanediylylidene))tetraaniline (Anthra-4Ph-4NH2). The synthesized had remarkable BET (BETSA) of 431 m2 g–1. Additionally, it exhibited outstanding thermal stability, shown by Td10 505 °C. Furthermore, practical implementation, demonstrates significant capacity capturing CO2, measuring 1.85 mmol g–1 at temperature 273 K 1 bar. In three-electrode test, has capacitance 121 F 0.5 A even after undergoing 5000 cycles, maintains retention rate 79%. Due to pore characteristics, N O, conjugation properties, this Anthtra-DHTP holds potential capture supercapacitor applications. work will pave way development materials based on postmodification additional groups, facilitating use in photodegradation, lithium battery applications,
