The high performance separation and pre-concentration of polar phenols from aqueous matrices is difficult because of the strong interactions between phenols and water molecules. Conjugated microporous polymers (CMPs) are a kind of novel porous organic materials. Polyphenylene core-conjugated microporous polymers (PPc-CMPs) were used as a novel coating material in the solid-phase microextraction of polar phenols in water samples for the first time. The novel PPc-CMPs fibers exhibited good thermal stability (>450 °C), high enrichment factors (519-2372), low limits of detection (0.02-0.05 ng L), wide linearity (0.1-1000 ng L), and good repeatability (2.5%-8.1%) for polar phenols. The new coating was successfully used in the analysis of phenols in real environmental water samples. PPc-CMPs as a polar solid-phase microextraction coating material was excellent for the rapid and sensitive analysis of phenols at trace levels in the environment.
由于酚类与水分子之间存在强烈相互作用，从水性基质中高效分离和预富集极性酚类具有一定难度。共轭微孔聚合物（CMPs）是一类新型多孔有机材料。聚苯撑核共轭微孔聚合物（PPc-CMPs）首次被用作水样中极性酚类固相微萃取的新型涂层材料。新型PPc-CMPs纤维对极性酚类表现出良好的热稳定性（>450 °C）、高富集因子（519 - 2372）、低检测限（0.02 - 0.05 ng L）、宽线性范围（0.1 - 1000 ng L）以及良好的重复性（2.5% - 8.1%）。这种新型涂层成功应用于实际环境水样中酚类的分析。PPc-CMPs作为一种极性固相微萃取涂层材料，对于环境中痕量酚类的快速、灵敏分析具有出色表现。
