Detection of hazardous compounds can alleviate risk to human health. However, it remains a challenge to develop easy-to-use testing tools for carcinogenic aromatic amines. Herein, we presented a conjugated molecule-based aniline detector, mixed matrix membranes (MMMs), through the solution-processable strategy. The pentacene-based dispersed phase is achieved using the state-of-the-art ionic liquids (ILs) as the continuous phase, based on which MMMs are easily manufactured by a solution process. Moreover, molecular dynamics (MD) simulations and quantum mechanical calculations suggested that hydrogen bonding and π-π interaction between ILs cations and pentacene could promote the dissolution. These prepared MMMs can offer easy-operation and on-site detection of carcinogenic primary aromatic amines with eye-readable fluorescence signal. This work provides a paradigm for the design of a portable testing device for various hazardous compounds.

检测有害化合物可以减轻对人类健康的风险。然而，开发易于使用的致癌芳香胺测试工具仍然是一个挑战。在这里，我们通过溶液可处理策略提出了一种基于共轭分子的苯胺检测器，混合基质膜 (MMM)。基于并五苯的分散相是使用最先进的离子液体 (ILs) 作为连续相来实现的，在此基础上，MMM 很容易通过溶液法制造。此外，分子动力学 (MD) 模拟和量子力学计算表明氢键和π - πILs阳离子和并五苯之间的相互作用可以促进溶解。这些制备的 MMM 可以提供易于操作和现场检测具有肉眼可读荧光信号的致癌伯芳香胺。这项工作为设计各种有害化合物的便携式测试装置提供了范例。
