Abstract Measuring anisotropic exciton transport in organic crystals goes beyond just assessing one‐dimensional (1D) transport. It offers a deeper understanding of how molecular packing and interactions affect different dimensions. However, achieving nanoscale precision measuring lengths linking them to specific crystalline directions remains formidable challenge. Here the development photoetching method is reported visualize distances as gaps within two‐dimensional (2D) crystals, which turn allows for use scanning electron microscope (SEM) precisely measure sizes. The combined with hetero‐seeded self‐assembly enables conventional fluorescence spectrometry precise determination 2D structures at nanoscale. Relying on this novel method, unexpectedly found that increasing intermolecular one crystal direction not only improves dimension but also enhances other dimension. These findings provide valuable insights engineering materials require efficient across extended distances.
