无论是在基础科学还是应用科学中，在微观和宏观水平上严格控制有序性和周期性的晶相复杂分子系统的设计对于开发新的固态材料和器件至关重要。设计和制造复杂的晶体系统，作为显示特定任务特性的晶体网络，是迈向智能材料的一步。在这里，我们报告的isostructural和几乎等距的不同颜色的分子晶体，它们用于制造核壳晶体，和它们的焊接通过3D外延生长成网络的晶体作为单晶实体。通过自组装过程将晶体焊接成宏观晶体网络是设计由显示目标特性的不同子域组成的分层组织的周期性复杂结构的有力策略。晶体焊接可以被认为是设计新的分层组织的复杂晶体系统的第一步。
Both for fundamental and applied sciences, the design of complex molecular systems in the crystalline phase with strict control of order and periodicity at both microscopic and macroscopic levels is of prime importance for development of new solid-state materials and devices. The design and fabrication of complex crystalline systems as networks of crystals displaying task-specific properties is a step toward smart materials. Here we report on isostructural and almost isometric molecular crystals of different colors, their use for fabrication of core shell crystals, and their welding by 3D epitaxial growth into networks of crystals as single-crystalline entities. Welding of crystals by self-assembly processes into macroscopic networks of crystals is a powerful strategy for the design of hierarchically organized periodic complex architectures composed of different subdomains displaying targeted characteristics. Crystal welding may be regarded as a first step toward the design of new hierarchically organized complex crystalline systems.
