Front Cover : In article number 2000723, Jiun‐Tai Chen and co‐workers present an effective strategy to prepare anisotropic polymer nanopillar arrays via photo‐fluidization. Azopolymers are first infiltrated into the nanopores of ordered anodic aluminum oxide templates. Upon exposure of linearly polarized lights, azobenzene groups in the azopolymers undergo trans‐cis‐trans photoisomerization, causing mass migration and elongation of the nanopillar along with the polarization directions.
