Precise quantifications of trace polycyclic aromatic hydrocarbons (PAHs) have been the focus in recent years due to the low concertation in environment and greatly potential damage on human health. The Rubrene (Rub) was used as the raw material to obtain a hyper-cross-linked polymer (HCP-Rub) via Friedel-Crafts reaction, which was further fabricated as a novel SPME coating. The abundant benzene rings on Rub could act as reactive sites, leading to the facile synthesis of HCP-Rub. Moreover, the as-prepared HCP-Rub possessed rich micropores, strong hydrophobicity and large conjugated structure, which made it an ideal candidate for the efficient enrichments of PAHs. The extraction efficiencies of HCP-Rub coated SPME fiber for PAHs were 1.5–16.4 times of the commercial PDMS fiber (100 μm), and 1.2–1.6 times of the commercial PDMS/DVB (65 μm) fiber, respectively. Under optimal conditions, the HCP-Rub coated fiber demonstrated high enhancement factors, ranging from 1331 to 3089. It was further coupled with gas chromatography-mass spectrometry (GC–MS) to establish an analytical method with wide linear ranges (5–1000 ng·L⁻¹) and low detection limits (0.11–0.98 ng·L⁻¹). Finally, the method was successfully applied to the determinations of trace PAHs in environmental water samples with good recoveries (83.7–108%).

微量多环芳烃 (PAHs) 的精确定量由于其在环境中的低协同性和对人体健康的潜在危害很大，近年来一直是关注的焦点。以红荧烯（Rub）为原料，通过途径获得超交联聚合物（HCP-Rub）Friedel-Crafts 反应，进一步制造为新型 SPME 涂层。Rub上丰富的苯环可以作为反应位点，导致HCP-Rub的轻松合成。此外，所制备的HCP-Rub具有丰富的微孔、强疏水性和大的共轭结构，使其成为高效富集PAHs的理想候选者。HCP-Rub 涂层固相微萃取纤维对 PAHs 的提取效率分别是商用 PDMS 纤维（100 μm）和商用 PDMS/DVB（65 μm）纤维的 1.5-16.4 倍和 1.2-1.6 倍。在最佳条件下，HCP-Rub 涂层纤维表现出高增强因子，范围从 1331 到 3089。它进一步与气相色谱-质谱 (GC-MS) 相结合，建立了具有宽线性范围 (5-1000 ng) 的分析方法·L^-1 ) 和低检测限 (0.11–0.98 ng·L ^-1 )。最后，该方法成功应用于环境水样中痕量多环芳烃的测定，回收率良好（83.7-108%）。
