During the last two decades, engineering motion with small-scale matter has received much attention in several areas of research, ranging from supramolecular chemistry and colloidal science to robotics and automation. The numerous discoveries and innovative concepts realized in motile micro- and nanostructures have converged in the field of small-scale swimmers. These man-made micro- and nanomachines can move in fluids by transforming different forms of energy to mechanical motion. Recently, metal–organic frameworks (MOFs), which are crystalline coordination polymers with high porosity, have been proposed as key building blocks in several small-scale swimmer designs. These materials possess the required features for motile micro- and nanodevices, such as high cargo-loading capacity, biodegradability, biocompatibility, and stimuli-responsiveness. In this review, we take a journey through the major breakthroughs and milestones realized in the area of MOF-based small-scale swimmers. First, a brief introduction to the field of small-scale swimmers is provided. Next, we review different strategies that have been reported for imparting motion to MOFs. Finally, we emphasize the incorporation of molecular machines into the MOF’s architecture as the means to create highly integrated small-scale swimmers. The strategies and developments explored in this review pave the way toward the use of motile MOFs for a variety of applications in the fields of biomedicine, environmental remediation, and on-the-fly chemistry.

运动中的金属有机框架

在过去的二十年中，小规模的工程运动在多个研究领域受到了广泛关注，从超分子化学和胶体科学到机器人技术和自动化。在能动的微米和纳米结构中实现的众多发现和创新概念已经在小型游泳者领域融合。这些人造的微型和纳米机器可以通过将不同形式的能量转换为机械运动来在流体中运动。最近，金属有机骨架（MOFs）是具有高孔隙率的结晶配位聚合物，已被提议作为几种小规模游泳运动员设计的关键组成部分。这些材料具有可移动的微型和纳米设备所需的功能，例如高载货能力，生物降解性，生物相容性和刺激响应能力。在这篇评论中，我们将探索基于MOF的小型游泳者领域中的重大突破和里程碑。首先，简要介绍了小型游泳者的领域。接下来，我们回顾了已报告的向MOF传递运动的不同策略。最后，我们强调将分子机器整合到MOF的体系结构中，以创建高度集成的小型游泳者。在这篇综述中探讨的策略和发展为在生物医学，环境修复和动态化学领域的各种应用中使用移动MOF铺平了道路。提供了小型游泳者领域的简要介绍。接下来，我们回顾了已报告的向MOF传递运动的不同策略。最后，我们强调将分子机器整合到MOF的体系结构中，以创建高度集成的小型游泳者。在这篇综述中探讨的策略和发展为在生物医学，环境修复和动态化学领域的各种应用中使用移动MOF铺平了道路。提供了小型游泳者领域的简要介绍。接下来，我们回顾了已报告的向MOF传递运动的不同策略。最后，我们强调将分子机器整合到MOF的体系结构中，以创建高度集成的小型游泳者。在这篇综述中探讨的策略和发展为在生物医学，环境修复和动态化学领域的各种应用中使用移动MOF铺平了道路。
