Graphical Abstract

Developing dual-responsive ultrathin polymersomes (UTPSs) is crucial for achieving intelligent nanodevices. In their Research Article (e202507852), Haibao Jin and co-workers report an innovative strategy for fabricating pH/visible light dual-responsive UTPSs with reversible acidochromism and fluorochromism performances via the self-assembly of amphiphilic alternating azocopolymers. 2D Quick Response code was meticulously crafted through incorporating these fluorescent UTPSs inks into the patterning lithography, displaying a multi-level decryption activity.
