从概念和应用的角度来看，在液体材料中设计明确的孔隙的可能性是令人着迷的。尽管多孔液体的概念于 2007 年提出，但由于合成相关的技术挑战，这些材料仍处于假设状态。然而，在过去五年中，基于现有多孔支架（例如配位笼、有机笼、金属有机框架、多孔碳、沸石和多孔聚合物）成功构建多孔液体的报道已经开始出现。在这里，重点是这些多孔液体作为现场原型的早期报告，根据先前定义的多孔液体类型进行分类。将特别关注设计策略和结构-性能关系。多孔液体已经在气体储存、运输和化学分离方面展现出有前景的应用。因此，它们在化学工业中显示出巨大的应用潜力。还将讨论制备、放大、挥发性、热稳定性和化学稳定性以及与多孔固体的竞争方面的挑战。
The possibility of engineering well-defined pores into liquid materials is fascinating from both a conceptual and an applications point of view. Although the concept of porous liquids was proposed in 2007, these materials had remained hypothetical due to the technical challenges associated with their synthesis. Over the past five years, however, reports of the successful construction of porous liquids based on existing porous scaffolds, such as coordination cages, organic cages, metal-organic frameworks, porous carbons, zeolites, and porous polymers, have started to emerge. Here, the focus is on these early reports of porous liquids as prototypes in the field, classified according to the previously defined types of porous liquids. Particular attention will be paid to design strategies and structure-property relationships. Porous liquids have already exhibited promising applications in gas storage, transportation, and chemical separations. Thus, they show great potential for use in the chemical industry. The challenges of preparation, scale-up, volatility, thermal and chemical stability, and competition with porous solids will also be discussed.
