We use synchrotron X-ray diffraction measurements to monitor the solvothermal crystallization mechanism of the aperiodic metal-organic framework TRUMOF-1. Following an initial incubation period, TRUMOF-1 forms as a metastable intermediate that subsequently transforms into an ordered product with triclinic crystal symmetry. We determine the structure of this ordered phase, which we call msw-TRUMOF-1, and show that it is related to TRUMOF-1 through topotactic reorganization of linker occupancies. Our results imply that the connectivity of TRUMOF-1 can be reorganized, as required for data storage and manipulation applications.
我们使用同步加速器X射线衍射测量来监测非周期性金属有机框架TRUMOF-1的溶剂热结晶机制。在初始潜伏期之后，TRUMOF-1以亚稳中间体的形式形成，随后转变为具有三斜晶体对称性的有序产物。我们确定了这个有序相的结构，将其称为msw-TRUMOF-1，并表明它通过连接体占据的拓扑重组与TRUMOF-1相关。我们的结果表明，TRUMOF-1的连接性可以根据数据存储和操作应用的需要进行重组。
