Two triphenylamine-based conjugated porous polymers, 1,3,5-triformylbenzene-4,4′4″-triaminotriphenylamine (TFB-TPA) and 2,4,6-triformylphloroglucinol-4,4′4″-triaminotriphenylamine (TFP-TPA) fabricated via Schiff-base reaction with π-conjugated skeletons and hierarchical pore structures were explored as adsorbents for the removal of gaseous toluene under humid environment. The effects of humidity, initial toluene concentration, adsorption temperature and surface functional groups on the adsorption capacity were investigated. The equilibrium isotherms, adsorption kinetics and structure-activity relationship were further analyzed. Experiment results suggest that the as-prepared TFB-TPA exhibits acceptable adsorption performance for gaseous toluene in humid atmosphere owing to the aromatic backbone and the hierarchically micro-meso-macroporous structure and the Freundlich equation agrees very well with the isothermal data, the pseudo-second-order kinetic model is more suitable to describe the adsorption kinetics. This study may not only show the application potential of triphenylamine-based conjugated porous polymers in toluene adsorption, but also provide a detailed understanding of the adsorption process of toluene for practical application.

两种基于三苯胺的共轭多孔聚合物1,3,5-三甲酰基苯-4,4'4''-三氨基三苯胺（TFB-TPA）和2,4,6-三甲酰基间苯三酚-4,4'4''-三氨基三苯胺（TFP-TPA探索了通过Schiff碱反应与π共轭骨架和分级孔结构制备的）作为在潮湿环境下去除气态甲苯的吸附剂。研究了湿度，甲苯初始浓度，吸附温度和表面官能团对吸附容量的影响。进一步分析了平衡等温线，吸附动力学和构效关系。实验结果表明，由于芳族骨架和分层的微介孔-宏观结构，所制备的TFB-TPA在潮湿气氛中对气态甲苯具有可接受的吸附性能，Freundlich方程与等温数据非常吻合，二阶动力学模型更适合描述吸附动力学。这项研究不仅可以表明三苯胺基共轭多孔聚合物在甲苯吸附中的应用潜力，而且可以为实际应用提供对甲苯吸附过程的详细理解。
