The ability to repeatedly record information with external stimuli, in particular light, is of fundamental importance for the development of photoresponsive materials. Here, we demonstrated a photo‐patterning system by using crosslinked azopolymers incorporatingmeta‐substituted azobenzene (M‐azo) moieties into dodecyl glyceryl itaconate (DGI) polymer networks. M‐azo inhibited H‐aggregation and showed efficienttrans‐to‐cisphotoisomerization in the crystal and film states, making photopatterning of the crosslinked polymers fully reversible. Macro‐ or microscale patterning could be written and erased in a reversible manner using light on the polymer film with fast response, high resolution, and flexibility. Moreover, these polymer films exhibited good fatigue resistance, which enabled hundreds of cyclic photo‐writing and erasing tests without any decay under alternating UV/Vis irradiation. The high fatigue resistance indicates the ability of the azopolymers to repeatedly harvest and convert light energy into chemical conformation in the polymer networks by taking advantages of efficient photoisomerization.
