A calix[4]arene acetylene (C4AE)-modified gold surface is successfully constructed in situ via click chemistry. The functionalized surface is used for selective recognition of paraquat by a wettability switch. Impedance measurements showed that the surface also expresses recognition for paraquat with a high sensitivity of 10 pM. The recognition mode, based on host-guest inclusion, is studied by computational calculations and the possible mechanism is analyzed.
通过点击化学，成功地在金表面原位构建了杯[4]芳烃乙炔（C4AE）修饰层。该功能化表面用于通过润湿性开关对百草枯进行选择性识别。阻抗测量表明，该表面对百草枯也具有高灵敏度的 10 pM 识别能力。通过计算计算研究了基于主客体包合的识别模式，并分析了可能的机制。
