The aim of the present review is to show how the phenomena of block copolymer self‐assembly and interactions of ionic (or ionizable) groups in polymer systems can be combined to produce materials with versatile and unique behavior. In our discussion, we consider two classes of tandem interactions. First, block copolymers containing short ionic blocks and long nonionic blocks are investigated in organic media. In systems of this type, block copolymer self‐assembly and short‐range electrostatic interactions act in tandem, forming regular and highly‐stable spherical structures. Next, we consider ionic (or ionizable) block copolymers dissolved in aqueous media. In this case, block copolymer self‐assembly acts in tandem with the hydrophilic nature of the soluble blocks, resulting in a wide range of unique morphologies.
