In organic chemistry, a Bechgaard salt is any one of a number of organic charge-transfer complexes that exhibit superconductivity at low temperatures.[1] They are named for chemist Klaus Bechgaard, who was one of the first scientists to synthesize them and demonstrate their superconductivity with the help of physicist Denis Jérome.[2] Most Bechgaard salt superconductors are extremely low temperature, and lose superconductivity above the 1–2 K range, although the most successful compound in this class superconducts up to almost 12 K.
All Bechgaard salts are formed using a small, planar organic molecule as an
All Bechgaard salts have a variation on a single tetrathiafulvalene motif—different superconductors have been made with appendages to the motif, or using a tetraselenafulvalene center instead (which is a related compound), but all bear this general structural similarity.
There are a wide range of other organic superconductors including many other charge-transfer complexes.
