利用绿色偶氮偶联反应在水中合成了一种含有大量游离酚羟基的多孔有机聚合物(标记为DT-POP),对其进行了表征,并将其作为去除水溶液中亚甲基蓝(MB)的有效吸附剂。永久介孔的存在、丰富的活性官能团以及苯环导致的π电子富集,使得DT-POP与阳离子染料MB具有强的氢键、π -π和静电相互作用,是一种高效的MB吸附剂。DT-POP具有高稳定性和高吸附能力,可多次重复使用,在污染物处理中具有很高的适用性。
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.
