Starting from neutral “pro‐ionomeric” diblock copolymers , photoluminescent benzobis(imidazolium) (BBI) dihalide salts are used to effect anion metathesis, affording fluorescent block ionomers in a single step. In aqueous media, the ionomers self‐assemble into either core‐ or shell‐crosslinked micellular structures, depending on the copolymer and BBI used (see figure).
