41-1: Strong Effect of Azodye Layer Thickness on RM-Stabilized Photoalignment

We have previously proposed a process for stabilizing azodye photo‐alignment layers using a surface localized reactive mesogen (RM) layer applied by dissolving the monomer in a liquid crystal prior to filling the cell. Surprisingly, thin azodye layers (~3 nm) exhibit improved stability upon exposure to polarized light compared to thicker layers (~40 nm).
