The integration of supramolecular chemistry with polymerization-induced self-assembly (PISA) offers a promising avenue to advance the design and functionality nanomaterials. Here, we elucidate role sulfone bonding in aqueous block copolymer (BCP) by evaluating PISA behaviors sulfone-functionalized BCPs stimuli-responsive properties resulting assemblies. A series 2-(alkylsulfonyl)ethyl acrylamides were designed for PISA, which moiety not only enhances monomer water solubility but also stabilizes polymer assemblies through bonding. Systematic variation alkyl tail revealed distinct behaviors, where shorter tails favored sulfone-bond-dominated assembly, while longer introduced competitive hydrophobic interactions. This interplay between hydrophobicity enabled fabrication programmable ion-responsive morphology transitions. Our findings provide fundamental insights into interactions establish versatile strategy engineering adaptive

Statistical copolymers have been extensively used in chemical industries and our daily lives, owing to their ease of synthesis functionalization. However, self-assembly based on statistical has haunted by high interfacial energy, poor stability, low concentration. We proposed the copolymerization-induced (
