一旦被认为是刚性的，静态的和不反应的，分子晶体越来越多地被认为表现出丰富的原子动力学，这在许多情况下导致材料对外部刺激具有适应性反应，如光，热和机械应力。这种范式转变促使了对动态晶体系统的研究的新领域，该动态晶体系统现在被认为是具有可切换特性的广泛功能材料的理想构建块，所述可切换特性例如机械、光学、光电、电子、磁性、结构特性和从纳米级到纳米级的动态行为。（例如，分子重新取向和异构化）到宏观尺度（例如，大块晶体跳跃、变形、形状改变）。1− 3由原子、分子和集体振动产生的晶格动力学被认为是这个复杂和多维功能景观的核心，尽管局部和远程振动、结构和功能之间的清晰联系还远未被理解。在这种情况下，晶体生长与设计中的虚拟特刊（VSI）旨在突出阐明晶格动力学在设计，开发和表征具有未开发特性的新动态分子晶体中的作用的最新努力。在这篇社论中，VSI的客座编辑强调了正在进行的和新兴的趋势，以及这个令人兴奋的领域的未来前景，以激发社区的兴趣，希望激发世界各地研究人员的新的多学科和协作努力，以揭示晶格动力学在决定晶体动态材料的性质和功能中的作用。
Once considered rigid, static, and unreactive, molecular crystals are increasingly recognized as exhibiting a rich set of atomic dynamics, which in many cases result in materials with adaptive responsiveness to external stimuli, such as light, heat, and mechanical stress. This paradigm shift has prompted a new area of research on dynamic crystalline systems that are now recognized as ideal building blocks for a broad range of functional materials with switchable properties, such as mechanical, optical, optoelectronic, electronic, magnetic, structural properties, and dynamic behaviors ranging from the nanoscale (eg, molecular reorientation and isomerization) up to the macroscopic scale (eg, bulk crystals jumping, deformation, shape-shifting). 1− 3 Lattice dynamics arising from atomic, molecular, and collective vibrations are believed to be at the core of this complex and multidimensional functional landscape even though clear connections between local and long-range vibrations, structures, and functions are far from being understood. In this context, this Virtual Special Issue (VSI) in Crystal Growth & Design aims to highlight the latest efforts to elucidate the role of lattice dynamics for the design, development, and characterization of new dynamic molecular crystals with unexplored properties. In this editorial, the guest editors of the VSI have highlighted ongoing and emerging trends, and future outlooks of this exciting field to spur the interest of the community, with the hope to stimulate new multidisciplinary and collaborative efforts of researchers around the world to uncover the role of lattice dynamics in dictating the properties and functions of crystalline dynamic materials.
