This work presents a simple and eco-friendly synthetic approach to fabricate a novel o-hydroxyazobenzene porous organic polymer (HAzo-POP) by diazo-coupling of 2,6-diaminoanthraquinone with m-trihydroxybenzene in aqueous solution. The prepared HAzo-POP possesses good stability and high adsorption capability towards aromatic organic pollutants due to its porous nature, highly conjugated structure and strong hydrogen bonding ability. The HAzo-POP was successfully used for the solid-phase extraction of phenylurea herbicides from six real samples prior to high performance liquid chromatography with ultraviolet detection. The analytical method showed good linearity in the range of 0.5-160.0 ng g for celery, lettuce and tomato samples, and 0.4-160.0 ng mL for milk, soybean milk and juice samples, with low limits of detection in the range from 0.05 to 0.30 ng g (or mL). The HAzo-POP has a promising application potential for the adsorption of more aromatic organic compounds.
本工作提出了一种简单且环保的合成方法，通过 2,6-二氨基蒽醌与间三苯酚在水溶液中的重氮偶联反应，制备了一种新型的邻羟基偶氮苯多孔有机聚合物（HAzo-POP）。由于其多孔性、高度共轭结构和强氢键能力，所制备的 HAzo-POP 对芳香族有机污染物具有良好的稳定性和高吸附能力。该 HAzo-POP 成功地用于高效液相色谱-紫外检测法前，从六种实际样品中固相萃取苯脲类除草剂。该分析方法在芹菜、生菜和番茄样品中 0.5-160.0ng g 范围内和牛奶、豆浆和果汁样品中 0.4-160.0ng mL 范围内具有良好的线性，检测限在 0.05 到 0.30ng g（或 mL）范围内。HAzo-POP 有望在吸附更多芳香族有机化合物方面具有应用潜力。
