Methodology development of robust linkages is fundamentally important for the synthesis and application of covalent organic frameworks (COFs). We report herein a new strategy based on multicomponent reactions (MCRs) to construct ultrastable COFs. With the one-pot formation of five covalent bonds in each cyclic joint, a series of imidazole-linked COFs were robustly constructed through the Debus-Radziszewski MCR from three easily available components. By reaching a higher level of complexity and precision in covalent assembly, this research explores a new direction in integrating sophisticated reversible/irreversible reactions to construct crystalline porous frameworks.
稳健连接的方法学发展对于共价有机框架（COF）的合成与应用至关重要。我们在此报告一种基于多组分反应（MCR）构建超稳定COF的新策略。通过在每个环状节点中一锅法形成五个共价键，利用德布斯-拉迪谢夫斯基多组分反应，从三种易于获得的组分中稳健地构建了一系列咪唑连接的COF。通过在共价组装中达到更高的复杂性和精度水平，本研究探索了整合复杂的可逆/不可逆反应以构建晶体多孔框架的新方向。
