The diverse chemical and structural properties of metal–organic frameworks (MOFs) make them attractive for myriad applications, but their native powder form is limiting for industrial implementation. Composite materials of MOFs hold promise as a means of exploiting MOF properties in engineered forms for real-world applications. While interest in MOF composites is growing, research to date has largely focused on utilization of single MOF systems. The vast number of different MOF structures provides ample opportunity to mix and match distinct MOF species in a single composite to prepare multifunctional systems. In this work, we describe the preparation of three types of multi-MOF composites with poly(vinylidene fluoride) (PVDF): (1) co-cast MOF MMMs, (2) mixed MOF MMMs, and (3) multilayer MOF MMMs. Finally, MOF MMMs are explored as catalytic membrane reactors for chemical transformations.

用于高级功能复合材料的多组分金属有机骨架膜†

金属有机骨架（MOF）的各种化学和结构特性使其在众多应用中具有吸引力，但它们的天然粉末形式限制了其工业应用。MOF的复合材料有望在实际应用中以工程化形式开发MOF特性。尽管对MOF复合材料的兴趣不断增长，但迄今为止的研究主要集中在单个MOF系统的利用上。大量不同的MOF结构提供了充足的机会，可以在单个复合物中混合和匹配不同的MOF物质，以制备多功能系统。在这项工作中，我们描述了三种类型的具有聚偏二氟乙烯（PVDF）的多MOF复合材料的制备：（1）共铸MOF MMM，（2）混合MOF MMM和（3）多层MOF MMM。最后，
