We have demonstrated a method to directly pattern organic light-emitting structures with a submicron resolution without any degradation in optical properties. Both small molecules and polymer-based light-emitting structures were patterned by nanoimprint at 150°C in a vacuum. The comparison of luminescence efficiency before and after patterning shows that nanoimprint did not cause degradation in the optical property of the materials. Nanoimprint offers a low-cost, high-throughput, high-resolution patterning technique that opens a way for realizing novel photonic devices based on organic light-emitting materials.
