✦ Synopsis

Reversibly photoswitchable proton transfer processes can occur between a three‐state molecular switch based on spiropyran (SP) and the “salt form” of polyaniline (see Figure), both in solution and in the solid state. As a result, the electrical conductivity of the thin‐film of SP‐doped polyaniline can be photoregulated.
