Front Cover : In article number 2000298 by Ziyu Liu, Jue Cheng, and Junying Zhang, an oligomer with four anthracene end groups has the ability of photoinduced solid‒liquid phase transition to prepare a reworkable adhesive. The generation and decomposition of [4+4] cycloaddition reaction which promotes the occurrence of solid‒liquid phase transition behavior are initiated by ultraviolet radiation of 365 and 254 nm, respectively. The lap shear strength and reworkable efficiency reach 2.4 MPa and 91.7% for quartz substrate.
