Perspective towards atomic‐resolution imaging of two‐dimensional polymers

Recent years have witnessed the rise of an emerging class synthetic two-dimensional (2D) materials-2D polymers. The combination organic chemistry and rational design polymeric crystals has stimulated tremendous research efforts in controlled synthesis 2D However, despite advancement methodologies, structural characterization polymers remains a significant challenge. Although aberration-corrected high-resolution transmission electron microscopy (AC-HRTEM) is capable direct imaging atomic structures with sub-Ångström resolution, radiation damage poses substantial limit on achievable image resolution due to instant decomposition molecular framework. In this Perspective, we will briefly discuss mitigation strategies, which may eventually result AC-HRTEM down scale.
