In order to realize functional devices based on light-matter interactions, we have focused on nano-photoisomerization of photochromic diarylethene molecules in single crystals. In this study, pathways formed by photoisomerization were partially eliminated by UV irradiation, and then pathways were formed again in the same region to evaluate the formation of multiple pathways. We also obtained correlation values for nano-optical structures with specific spatial frequencies to determine the characteristics of forgetting and multiple memory of the memory structures of the photoisomerization pathways.
