挥发性脂肪醛类化合物具有化学毒性、物理挥发性和广泛的应用前景，其检测具有重要意义。在这项工作中，脂肪醛的直接检测解决了使用柱[5]芳烃基荧光超分子聚合物与气相变色行为。将线性超分子聚合物涂覆在玻璃片上，制备了具有强橙黄色荧光的薄膜。当薄膜暴露于不同碳链长度的脂肪醛时，它们可以选择性地感测正丁醛（C-4）和辛醛（C-8），并伴有荧光猝灭，表明该超分子聚合物是一种对长烷基链脂肪醛具有高选择性的汽相变色响应材料。
The detection of volatile aliphatic aldehydes is of significance because of their chemical toxicity, physical volatility and widespread applications in chemical industrial processes. In this work, the direct detection of aliphatic aldehydes is tackled using a pillar[5]arene-based fluorescent supramolecular polymer with vaporchromic behavior. Thin films with strong orange-yellow fluorescence are prepared by coating the linear supramolecular polymer on glass sheets. When the thin films are exposed to aliphatic aldehydes with different carbon chain lengths, they can selectively sensing n-butyraldehyde (C-4) and caprylicaldehyde (C-8), accompanied by fluorescence quenching, indicating that the supramolecular polymer is a highly selective vapochromic response material for aliphatic aldehydes with long alkyl chains.
