开发高效去除水污染物的吸附剂对环境保护具有重要意义。在这项研究中，含有分子内氢键模式的共轭三芳基三嗪(CTT)被认为是构建多孔有机聚合物(POP)吸附剂的有趣构件。这些具有多个酚羟基的平面单体有助于形成具有层次化多孔结构、片状形貌、良好的表面润湿性和高度官能化的氮杂连接聚合物。CTT-POP吸附剂的这种结构特性提供了从水中超快吸附各种阳离子染料的能力。CTT-POP-1对亚甲基蓝染料的吸附，其准二级速率常数为12.9g mg~(-1)·min~(-1)，优于现有文献报道的结果。此外，CTT-POP-1可以至少再生7次而不损失性能，表明其在水处理中具有潜在的应用前景。
Developing efficient adsorbents for the removal of water pollutants is of great significance for environmental protection. In this study, conjugated triaryl triazines (CTT), containing intramolecular hydrogen-bonding patterns, were recognized to be intriguing building blocks for the construction of porous organic polymer (POP) adsorbents. These planar monomers with multiple phenolic hydroxyl groups facilitated the formation of aza-linked polymers with hierarchical porous structures, sheet-like morphology, good surface wettability, and high degree of functionality. Such structural characteristics of the CTT-POP adsorbents provided superfast adsorption of various cationic dyes from water. For the adsorption of methylene blue dye, the pseudo-second-order rate constant of CTT-POP-1 is 12.9 g mg-1 min-1, superior to those reported in the existing literature. In addition, CTT-POP-1 can be regenerated at least seven times with no loss in performance, indicating its potential application in water treatment.
