Since the late 1990s, much progress has been made in the field of the chemistry of flexible porous coordination polymers (PCPs). Various PCP architectures have been recognized and several promising applications have been identified, e.g., in the areas of selective gas capture and separation, sensors, and drug carriers. The crystalline and flexible frameworks of PCPs can respond to various external stimuli and then adjust themselves to adapt to new environments in a tuneable fashionࣧ behavior that is seldom observed in other porous solids. Over the past decade, following on from developments made in terms of flexible PCP performance, how to accurately build these architectures with the required functions has become a new challenge. In this review, the authors focus on the three aspects of flexible PCPs: 1) classifying the flexible systems with different fashions of pore opening, 2) classifying the flexible PCPs with governing factors of internal structure and external conditions, and 3) introducing, and summarizing, flexibility- and structure-dependent performance. The goal is to present the state-of-art chemistry and application of flexible PCPs and to offer an outlook towards discovering and designing further new materials.

自 1990 年代后期以来，柔性多孔配位聚合物 (PCP) 的化学领域取得了很大进展。各种 PCP 架构已得到认可，并且已经确定了几种有前景的应用，例如，在选择性气体捕获和分离、传感器和药物载体等领域。PCP 的结晶和柔性框架可以对各种外部刺激做出反应，然后调整自己以适应新环境，以可调节的方式适应新环境，这在其他多孔固体中很少观察到。近十年来，随着PCP灵活性能的发展，如何准确地构建具有所需功能的这些架构已成为一个新的挑战。在这篇综述中，作者关注灵活 PCP 的三个方面：1) 对具有不同开孔方式的柔性系统进行分类，2) 根据内部结构和外部条件的控制因素对柔性 PCP 进行分类，以及 3) 介绍和总结柔性和结构相关的性能。目标是展示柔性 PCP 的最先进化学和应用，并提供发现和设计更多新材料的前景。
