Counterion-Mediated Self-Assembly of Ion-Containing Block Copolymers on the Basis of the Hofmeister Series

A Cl − and I − ion‐containing amphiphilic diblock copolymer [PEO‐ b ‐P(qVBC‐ co ‐St)], IBCP , which comprises the poly(ethylene oxide) block and poly(quaternized 4‐vinylbenzyl chloride‐ co ‐styrene) is prepared by sequence reactions. Then the counterion‐mediated self‐assembly behavior in aqueous solution is investigated in detail. The hydrophilicity of anion containing units (qVBC) is controlled by the nature of the different counterions after...
