Radical Anion Salts of Naphthalenetetracarboxylic Acid Derivatives—a Novel Class of Electrically Conducting Compounds

The search for new organic conductors has led to a broadly variable class consisting of the radical anion salts of naphthalenetetracarboxylic dianhydride and diimide. The X‐ray structure analysis of the complex 1 (single crystal conductivity σ20°C = 10 S cm−1) revealed a stacking of anionic units characteristic of one‐dimensional conductors.
