尽管共价有机骨架（COFs）有多种骨架可用，但对孔隙表面润湿性的控制仍然不发达，这可以极大地扩展它们的整体通用性。在此，我们提出了一种有效的策略，通过在孔表面化学涂覆全氟烷基来赋予COFs超润湿性，使其具有超疏水性。利用可控改性，合成的COFs保留了原始COFs的孔隙度和结晶度。得益于COF晶体的整体超疏水性和COF合成的可行性，它们可以用作涂层或原位集成在各种衬底中；一旦应用，这使得它们具有超疏水性。考虑到模块化的性质，该协议与各种特定润湿性的发展相兼容，从而构成了扩大COF应用范围的一步，并为先进材料和设备的加工提供了许多机会。
Despite the availability of a variety of skeletons for covalent organic frameworks (COFs), control of pore-surface wettability remains undeveloped, which could immensely expand their overall versatility. Herein, we contribute an effective strategy for imparting super wettability on COFs by chemically coating the pore surface with perfluoroalkyl groups to confer them with superhydrophobicity. Taking advantage of controllable modification, the resultant COFs retain the porosity and crystallinity of the pristine COFs. Benefiting from the bulk superhydrophobicity of the COF crystals and the feasibility of COF synthesis, they can be used as a coat or in situ integrated within various substrates; once applied, this renders them superhydrophobic. Given the modular nature, this protocol is compatible with the development of various specific wettabilities in COFs, which thereby constitutes a step for expanding the scope of COF applications and provides many opportunities for the processing of advanced materials and devices.
