Functional and externally controllable electroactive nanostructures are obtained by an ionic self‐assembly process. 2D rectangular columnar structures (see picture) comprising oligoanilines were prepared by complexation with double‐tail phosphate surfactants. Upon heating, tetraaniline complexes show an order–disorder transition from this 2D phase structure to a disordered state as a reversible change in the electrical conductivity.
