Light‐induced solid‐liquid phase transition materials have attracted considerable attention because of their potential applications, such as reworkable adhesives, selfhealing materials, and transfer printing. In their report on page 568, Ito, Akiyama, and coworkers report a new family of such phase transition materials, azobenzene‐based poly(vinyl ether)s, and demonstrate that the flexible polymer backbone improves the order of alignment of the mesogenic azobenzene, leading to solid‐liquid phase transition materials with high thermal stability. The cover image shows a liquid crystalline phase of the trans‐azobenzene polymer and UV‐induced photomelting. (DOI: 10.1002/pol.20190153 ).
