Metal-organic frameworks (MOFs) are normally moisture-sensitive and unstable in aqueous environments, which has considerably limited their practical applications because water/moisture is ubiquitous in many industrial processes. New materials with superior water stability are, therefore, in great demand and vital to their practical applications. Here, a novel oil/water interfacial assembly strategy is demonstrated for the synthesis of a new class of metal-organic monoacid framework (MOmAF) with exceptional water stability and chemical stability. Superhydrophobic 2D sheets are synthesized at room temperature, while 1D nanotubes are obtained via the self-scrolling of their 2D sheets for the first time. In addition, a simple sequential drop-casting method is developed to coat as-synthesized MOmAF structures onto porous membranes. This can potentially open up new avenues in the design of superhydrophobic self-cleaning MOmAF materials without tedious post-synthetic modifications and usher in a new class of materials meeting industrial needs.
金属有机框架材料（MOFs）通常对水分敏感，在水环境中不稳定，这在很大程度上限制了它们的实际应用，因为水/湿气在许多工业过程中普遍存在。因此，具有优异水稳定性的新材料需求巨大，对其实际应用至关重要。在此，展示了一种新颖的油/水界面组装策略，用于合成一类具有卓越水稳定性和化学稳定性的新型金属有机单酸框架（MOmAF）。在室温下合成超疏水二维片材，同时首次通过其二维片材的自卷曲获得一维纳米管。此外，开发了一种简单的顺序滴铸法，将合成的MOmAF结构涂覆到多孔膜上。这有可能为超疏水自清洁MOmAF材料的设计开辟新途径，而无需繁琐的合成后修饰，并引入一类满足工业需求的新型材料。
