报告摘要:
Understanding the three-dimensional arrangement of atoms is fundamental to elucidating the properties and functions of molecules and materials. While X-ray crystallography remains the cornerstone of structural analysis, it faces significant limitations when applied to nano- and micro-crystals, as well as complex polycrystalline samples. Despite advances in high-throughput synthesis and data-driven materials design, the structural characterization of polycrystalline powders continues to be a major bottleneck.
Electron crystallography offers unique advantages for studying crystals that are too small, too beam-sensitive, or too complex for X-ray diffraction. In this lecture, I will present several high-throughput electron diffraction methods developed in my group, including continuous rotation electron diffraction , serial electron diffraction , and serial rotation electron diffraction. These techniques have enabled the structural analysis of a broad range of materials—from inorganic porous frameworks such as zeolites and metal-organic frameworks, to pharmaceutical polymorphs—at atomic resolution.
I will demonstrate how high-throughput automated data collection and analysis allow not only the study of extremely beam-sensitive crystals but also phase identification and the detection of minor phases that remain undetectable by conventional X-ray diffraction. Moreover, electron diffraction enables the visualization of fine structural features such as hydrogen positions, framework disorders, linker dynamics in MOFs, host–guest interactions, and structural transformations.
We envision that the development of automated pipelines will transform electron diffraction into a fast, reliable, and accessible characterization technique that can be adopted even by researchers without specialized training in TEM or crystallography. The integration of these emerging methods has already begun to reshape the field of crystallography and offers unprecedented opportunities for discovering novel materials, resolving complex structures, and probing structure–property relationships.
