A porous organic polymer (marked as DT-POP), which contains abundant free phenolic hydroxyl groups, is synthesized by the well-known green azo-coupling reaction in water, characterized, and utilized as an effective adsorbent for the elimination of methylene blue (MB) from water solutions. The presence of permanent mesopores, abundant active functional groups, and π-electron enrichment ascribed to phenyl rings make DT-POP an efficient adsorbent for MB due to strong hydrogen bonding, π–π, and electrostatic interactions with the cationic dye MB. DT-POP with high stability and high adsorption capacity can be reused many times and thus shows high applicability in pollutant disposal.

绿色重氮偶联反应合成多孔有机聚合物吸附去除亚甲基蓝



通过水中著名的绿色偶氮偶联反应合成了含有丰富游离酚羟基的多孔有机聚合物(标记为DT-POP),并对其进行了表征,并将其用作消除亚甲基蓝的有效吸附剂。 MB)来自水溶液。永久介孔、丰富的活性官能团以及苯环带来的 π 电子富集的存在,使 DT-POP 由于与阳离子染料 MB 的强氢键、π-π 和静电相互作用而成为 MB 的有效吸附剂。 DT-POP具有高稳定性和高吸附能力,可多次重复使用,在污染物处理中表现出很高的适用性。
