晶体分子机器代表了晶体工程和材料科学的一个令人兴奋的新分支，对纳米技术具有重要意义。晶体分子机器是由分子构建的晶体，这些分子在结构上被编程为集体响应机械，电，磁或光子刺激以实现特定功能。它们的构造中的主要挑战之一来自于它们在晶体固体的紧密堆积、自组装环境中的机械操作所需的皮米级精度。在这篇文章中，我们概述了一些一般的指导方针，他们的设计和应用它们的分子晶体的建设单位旨在模拟宏观陀螺仪和指南针。这些有趣的系统的制备，结晶和动态表征的最新进展提供了一个立足点的可能性，并有助于突出未来实验的一些途径。
Crystalline molecular machines represent an exciting new branch of crystal engineering and materials science with important implications to nanotechnology. Crystalline molecular machines are crystals built with molecules that are structurally programmed to respond collectively to mechanic, electric, magnetic, or photonic stimuli to fulfill specific functions. One of the main challenges in their construction derives from the picometric precision required for their mechanic operation within the close-packed, self-assembled environment of crystalline solids. In this article, we outline some of the general guidelines for their design and apply them for the construction of molecular crystals with units intended to emulate macroscopic gyroscopes and compasses. Recent advances in the preparation, crystallization, and dynamic characterization of these interesting systems offer a foothold to the possibilities and help highlight some avenues for future experimentation.
