Fully-aromatic, two-dimensional covalent organic frameworks (2D COFs) are hailed as candidates for electronic and optical devices, yet to-date few applications emerged that make genuine use of their rational, predictive design principles and permanent pore structure. Here, we present a 2D COF made up of chemoresistant β-amino enone bridges and Lewis-basic triazine moieties that exhibits a dramatic real-time response in the visible spectrum and an increase in bulk conductivity by two orders of magnitude to a chemical trigger - corrosive HCl vapours. The optical and electronic response is fully reversible using a chemical switch (NH3 vapours) or physical triggers (temperature or vacuum). These findings demonstrate a useful application of fully-aromatic 2D COFs as real-time responsive chemosensors and switches.

全芳香族二维共价有机框架（2D covalent organic framework, 2D COF）被推崇为电子与光电器件的极具潜力的候选材料，但迄今为止鲜有应用能真正利用其可理性设计、可预测的构建原则与永久孔道结构。本文报道了一种由耐化学腐蚀的β-氨基烯酮桥联单元与路易斯碱性三嗪基团构成的二维共价有机框架，该材料在可见光谱范围内呈现出显著的实时响应，且在腐蚀性氯化氢蒸气的化学刺激下，其体相电导率提升了两个数量级。通过化学开关（氨气蒸气）或物理刺激（温度或真空环境）可实现该光电子响应的完全可逆性。上述研究成果证实，全芳香族二维共价有机框架可作为实时响应型化学传感器与开关器件，具备切实可行的应用价值。
