MicroED as a powerful technique for the structure determination of complex porous materials

Received Date: 15 October 2023

Porous materials have garnered significant attention in recent years. Understanding the intrinsic relationship between their structures and properties requires precise knowledge of their atomic structures. Single-crystal X-ray diffraction (SCXRD) has traditionally been the primary method for elucidating such structures, but it demands large, high-quality crystals, often exceeding 5 μm in size. The growth of these crystals can be a time-consuming process, especially for one- and two-dimensional materials. To explore structures at the nanoscale, MicroED (microcrystal electron diffraction (ED)) offers unprecedented insights into the realm of nanomaterials. This revolutionary technique enables researchers to uncover intricate details within nanoscale structures, promising to reshape our fundamental understanding of materials. In this review, we delve into the applications of MicroED in the study of various porous materials, including zeolites, metal-organic frameworks (MOFs), and covalent organic frameworks (COFs). We emphasize the pivotal role of MicroED in nanomaterial characterization, enabling precise crystallographic analysis and phase identification.
