Three novel conjugated porous organic polymers, denoted as C-POP1–3 and which consist of alternating pyrene cores with various contorted fluorene surrogates, were successfully synthesized from a versatile one-pot palladium-catalyzed [3+2] cyclocondensation reaction. The resulting polymers obtained in excellent yields displayed weight-average molecular weights (Mw) ranging 12.2 to 20.2 kg/mol polydispersity indices (Mw/Mn) between 1.8 2.4, suggesting that the masses are narrowly distributed thus implying homogeneous polymer chains. Thermal stability exploration by thermogravimetric analysis (TGA) revealed an impressive robustness 10% weight reduction temperature attaining 485 °C. Investigation inherent microporosity properties via nitrogen adsorption experiments using Brunauer–Emmett–Teller (BET) theory discloses their surface areas reach up 560 m2 g–1 pore volumes averaging 0.47 cm3 g–1. target explored adsorbents disclosing maximum carbon dioxide 83.0 mg at 273 K low pressure for C-POP1, whereas iodine sorption tests portrayed prominent outcomes, notably C-POP3 proved owe strong affinity toward hitherto mentioned halogen achieving 2220 Additionally, recyclability confirmed possibility regenerate polymers' capabilities even after seven consecutive cycles adsorption–desorption cycles, qualify them auspicious adsorbents.

Polyhydroxy-azo Porous Organic Polymers for Efficient Removal of Organic Pollutants from Water

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(10), С. 5674 - 5683

Опубликована: Апрель 10, 2024

Effective adsorption and separation of organic pollutants from wastewater are essential to protecting the environment human health. In this study, porous polymers (PAPOPs) containing a tri(polyhydroxy-phenyl-azo-phenyl) benzene skeleton structure were synthesized through diazotization coupling without any catalyst participation. It was found that PAPOPs have high specific surface area, mesoporous structure, good thermal stability, electronegativity. Based on these characteristics, demonstrated maximum capacity 1773.15 mg g–1 for rhodamine B (RhB), 1091.75 Congo red, 306.33 tetracycline hydrochloride. Furthermore, also exhibited selectivity an extremely fast rate RhB. The efficiency did not significantly decrease even after seven repeated uses, indicating their broad application prospects in treatment.
