The structural characterization of sublayer surfaces of MIL‐101 is reported by low‐dose spherical aberration‐corrected high‐resolution transmission electron microscopy (HRTEM). The state‐of‐the‐art microscopy directly images atomic/molecular configurations in thin crystals from charge density projections, and uncovers the structures of sublayer surfaces and their evolution to stable surfaces regulated by inorganic Cr 3 (μ 3 ‐O) trimers. This study provides compelling evidence of metal–organic frameworks (MOFs) crystal growth via the assembly of sublayer surfaces and has important implications in understanding the crystal growth and surface‐related properties of MOFs.
