Synthesis of a Novel Oligoaniline: “Dumbbell‐Shaped” Oligoaniline

Summary: A new kind of aniline oligomer with a “dumbbell” shape was synthesized through a simple oxidative coupling reaction with a new rigid aromatic amine as starting material. The oligomer was characterized with mass spectrometry, IR and NMR spectroscopies. Its redox property was checked by cyclic voltammetry and chemical oxidation/reduction process was monitored by UV spectroscopy. We found it has a reversible electrochemical property like common oligoanilines. Combined with its well‐defined structure, it is expected to act as a model compound for a molecular electronic switch.
