Recently, one paper published on Macromolecules was selected as the journal cover (Macromolecules 2022, 55, 20, 9091–9102). The cover picture shows the reversibility and reconstruction ability of the dynamically cross-linked polymer network. The blue wear gear-like shape connected to the red cylindrical shape represents the dynamic cross-linking points based on conjugated and hindered urea bonds. The three units in the circle represent the tunable chain structures between cross-linking points. 

  The first author of the paper is Prof. Yu Li and the corresponding author is Prof. Xinli Jing.
