近年来，对框架材料的研究有了很大的增加，包括现在普遍存在的金属有机框架，以及密集配位聚合物、共价有机框架和分子框架。随着合成和表征的结构数量的迅速增加，柔性化的现象越来越普遍。更具体地说，许多重要的框架材料具有刺激响应性：它们的结构可以在响应物理或化学刺激时发生大幅度的变化。它们可以显示由温度、机械压力、客体吸附或疏散、光吸收等引起的转变，有时被称为智能材料、软晶体或动态材料。本展望强调了该领域的最新进展，展示了一些最新颖和不寻常的刺激反应，以及对柔性框架材料的基本理解的进展。
Recent years have seen a large increase of the research effort focused on framework materials, including the nowadays-ubiquitous metal organic frameworks but also dense coordination polymers, covalent organic frameworks, and molecular frameworks. With the quickly increasing number of structures synthesized and characterized, one pattern emerging is the common occurrence of flexibility. More specifically, an important number of framework materials are stimuli-responsive: their structure can undergo changes of large amplitude in response to physical or chemical stimulation. They can display transformations induced by temperature, mechanical pressure, guest adsorption or evacuation, light absorption, etc. and are sometimes referred to as smart materials, soft crystals, or dynamic materials. This Perspective highlights recent progress in this field, showcasing some of the most novel and unusual responses to stimuli, as well as advances in the fundamental understanding of flexible framework materials.
