Outside Back Cover: Selective Synthesis of [2]Rotaxane Orientational Isomers With Precisely Arranged Luminogens: Toward Orientation‐Dependent Emissions for Information Storage and Encryption

In the Research Article e3759413, Xu-Qing Wang, Wei Wang, and co-workers report a steric hindrance-controlled selective stopper exchange strategy for the precise synthesis of six pairs of [2]rotaxane orientational isomers. The cover depicts luminogen-arranged isomers exhibiting orientation-dependent emissions, particularly in circularly polarized luminescence. This work establishes a versatile platform for constructing chiral luminescent materials with promising applications in information storage and encryption.
