Flexible porous frameworks are at the forefront of materials research. A unique feature is their ability to open and close their pores in an adaptive manner induced by chemical and physical stimuli. Such enzyme-like selective recognition offers a wide range of functions ranging from gas storage and separation to sensing, actuation, mechanical energy storage and catalysis. However, the factors affecting switchability are poorly understood. In particular, the role of building blocks, as well as secondary factors (crystal size, defects, cooperativity) and the role of host-guest interactions, profit from systematic investigations of an idealized model by advanced analytical techniques and simulations. The review describes an integrated approach targeting the deliberate design of pillared layer metal-organic frameworks as idealized model materials for the analysis of critical factors affecting framework dynamics and summarizes the resulting progress in their understanding and application.
柔性多孔框架处于材料研究的前沿。其独特之处在于它们能够在化学和物理刺激诱导下以自适应方式打开和关闭孔隙。这种类似酶的选择性识别提供了广泛的功能，从气体存储与分离到传感、驱动、机械能存储和催化。然而，影响可切换性的因素却知之甚少。特别是，构建单元的作用，以及次要因素（晶体尺寸、缺陷、协同作用）和主客体相互作用的作用，受益于通过先进分析技术和模拟对理想化模型进行的系统研究。这篇综述描述了一种综合方法，旨在精心设计柱状层金属有机框架作为理想化模型材料，用于分析影响框架动力学的关键因素，并总结了在理解和应用方面所取得的进展。
