我们报道了金表面乙酰基终止的自组装单分子膜(SAM)对“点击”化学的反应性，即惠氏1，3-偶极加成，导致三氮唑的形成。在乙酰基封端的自组装膜形成后，在自组装膜上进行三氮唑的形成，并通过傅立叶变换红外光谱、X射线光电子能谱、椭偏仪和接触角测角仪对反应进行了确认。Click化学为溶液化学中的官能化提供了一种通用的策略，反应条件温和，官能团具有很高的相容性，我们的结果表明，该反应可以应用于乙炔封端的自组装膜，在表面引入有用的官能团。
We report the reactivity of acetylenyl-terminated self-assembled monolayers (SAMs) on gold toward "click" chemistry, Huisgen 1,3-dipolar addition, leading to the formation of triazoles. After the formation of acetylenyl-terminated SAMs, the triazole formation was performed on the SAMs and the reaction was confirmed by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, ellipsometry, and contact angle goniometry. "Click" chemistry has offered a versatile strategy for the functionalization in solution chemistry with mild reaction conditions and a high compatibility in functional groups, and our result shows that the reaction could be applied to acetylenyl-terminated SAMs for the introduction of useful functional groups to the surfaces.
