Back Cover: A large increase in the magnitude of the photogenerated stress is observed in a crosslinked azobenzene‐functionalized polyimide. Subjecting the material to pre‐strain aligns the azobenzene units in the polyimide, which serves to enhance the cooperative motion of the photo chemical mechanism to yield a photogenerated stress of 1.25 MPa. This value is more than two times larger than the stress generated in the “as‐prepared” polyimide. Further details can be found in the article by K. M. Lee, D. H. Wang, H. Koerner, R. A. Vaia, L.‐S. Tan,* and T. J. White* on page 1189 .
