Metal-organic frameworks (MOFs), also known as coordination polymers (CPs), are crystalline materials constructed from metal ions or clusters bridged by organic ligands to form one-, two-, or three-dimensional infinite networks. In contrast with the prolific production of MOFs based on rigid ligands (RL-MOFs), the design, syntheses and applications of MOFs based on flexible ligands (FL-MOFs) are somewhat overlooked. Although sacrificing a measure of control, the use of flexible ligands may provide unique opportunities to obtain novel crystalline framework materials exhibiting desirable attributes. In this review, emphasis has been placed on the design and the structural diversity of FL-MOFs. Homochiral FL-MOFs and dynamic frameworks induced by flexible ligands are also briefly outlined. An overview is also shown for the applications of FL-MOFs as platforms for gas adsorption, heterogeneous catalysis, proton conduction etc.
金属-有机骨架（MOFs），也称为配位聚合物（CPs），是由金属离子或簇通过有机配体桥接而成的结晶材料，可形成一维、二维或三维的无限网络。与大量基于刚性配体（RL-MOFs）的 MOFs 的生产相比，基于柔性配体（FL-MOFs）的 MOFs 的设计、合成和应用有些被忽视。尽管牺牲了一定程度的控制，但使用柔性配体可能会提供独特的机会，获得具有理想属性的新型结晶骨架材料。在本综述中，重点介绍了 FL-MOFs 的设计和结构多样性。还简要概述了手性 FL-MOFs 和由柔性配体诱导的动态框架。还展示了 FL-MOFs 在气体吸附、多相催化、质子传导等方面作为平台的应用。
