Pore space partition (PSP) concept is a synthetic design concept and can also serve as a structure analysis method useful for next-step synthetic planning and execution. PSP provides an integrated chemistry-topology-focused tool to design new materials platforms. While PSP is no less effective for making large-pore materials, the growing importance of small-molecule gas storage and separation for green-energy applications provides impetus for developing small-pore materials for which the PSP strategy is uniquely suited. Currently, the best embodiment of the PSP concept is the partitioned-acs (pacs) platform in which both fine or coarse adjustments to the building blocks have sparked a transformation of a prototype framework into a huge and continuously expanding family of chemically robust materials with controllable pore metrics and functionalities suitable for tailored applications. The pacs compositional diversity results from the platform's intrinsic multi-module nature, geometric flexibility and tolerance towards individual module variations, and mutual structure-directing effects among various modules, all of which combine to enable the molecular-level uniform co-assemblies of chemical components rarely seen together elsewhere. In this contribution, we present an overview of different pore space engineering methods and how different MOF materials have contributed to important advances in chemical stability, industrial gas storage and gas separation. In particular, we will focus on synthetic assembly of the pacs system, highlighting the differences of pacs materials from other MOF platforms and advantages of pacs materials in enhancing various MOF properties.

孔隙空间分区（PSP）概念是一种综合设计概念，也可以作为一种结构分析方法，对下一步综合规划和执行很有用。PSP 提供了一个以化学拓扑为重点的集成工具来设计新材料平台。虽然 PSP 在制造大孔材料方面同样有效，但小分子气体储存和分离在绿色能源应用中的重要性日益增加，这为开发特别适合 PSP 策略的小孔材料提供了动力。目前，PSP 概念的最佳体现是 partitioned-acs ( pacs) 平台，其中对构建块的精细或粗略调整已引发原型框架转变为庞大且不断扩展的化学稳健材料系列，这些材料具有可控的孔隙指标和功能，适合定制应用。pacs _组成多样性源于平台固有的多模块性质、几何灵活性和对单个模块变化的容忍度，以及各个模块之间的相互结构导向效应，所有这些结合起来，使化学成分的分子水平均匀共组装成为罕见在别处一起。在这篇文章中，我们概述了不同的孔隙空间工程方法，以及不同的 MOF 材料如何为化学稳定性、工业气体储存和气体分离方面的重要进展做出贡献。特别是pacs系统的合成组装，突出pacs材料与其他MOF平台的差异和pacs的优势增强各种 MOF 性能的材料。
