Self‐Assembly and Electrical Conductivity Transitions in Conjugated Oligoaniline–Surfactant Complexes

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.
