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

Abstract Although artificial oxygen carriers have been extensively developed, successful mimicry of erythrocytes in both morphology and oxygen‐binding properties has rarely achieved. Herein, biconcave disc‐shaped vesicles (BDVs) with capacity are created as through polymerization‐induced self‐assembly, utilizing a binary mixture stabilizer blocks distinct solvent affinities. The affinities induced microphase separation, resulting inhomogeneous surface tension across the vesicle membrane potentially causing spherical to deform into an erythrocyte‐like morphology. core‐forming block BDVs, high fluorocarbon content, enables capacity. Furthermore, can be engineered carry functional molecules, such porphyrins, alongside their role carriers. It is believed that this work will provide valuable insights biomimicry structure function.
