人工分子机器能够响应化学或物理触发来产生和利用精确的纳米级驱动。最近的科学努力致力于分子机器的大型组件的集成，定向和接口连接，以便在更大的长度范围内利用它们的集体驱动，直至产生宏观运动。利用这样的“层次力学”代表了一种刺激响应材料概念的根本新方法。此外，因为某些分子机器可以充当分子电动机，它们能够使单向运动脱离热力学平衡并逐渐增加传递到其环境中的功，所以人们可以期望有独特的机会来设计能够自主控制的新型机械活性材料和装置由外部能源供应时的行为。总结了最近报道的成就，包括在3D自组装材料以及液晶和聚合物材料中将分子机器集成在表面和界面上。讨论了它们的详细功能原理及其功能特性，以及它们在各个领域的潜在应用，例如传感，药物输送，电子，光学，等离子和力学。

From Molecular Machines to Stimuli-Responsive Materials.

Artificial molecular machines are able to produce and exploit precise nanoscale actuations in response to chemical or physical triggers. Recent scientific efforts have been devoted to the integration, orientation, and interfacing of large assemblies of molecular machines in order to harness their collective actuations at larger length scale and up to the generation of macroscopic motions. Making use of such "hierarchical mechanics" represents a fundamentally new approach for the conception of stimuli-responsive materials. Furthermore, because some molecular machines can function as molecular motors-which are capable of cycling a unidirectional motion out of thermodynamic equilibrium and progressively increasing the work delivered to their environment-one can expect unique opportunities to design new kinds of mechanically active materials and devices capable of autonomous behavior when supplied by an external source of energy. Recently reported achievements are summarized, including the integration of molecular machines at surfaces and interfaces, in 3D self-assembled materials, as well as in liquid crystals and polymer materials. Their detailed functioning principles as well as their functional properties are discussed along with their potential applications in various domains such as sensing, drug delivery, electronics, optics, plasmonics, and mechanics.
