Abstract
Many investigations have been made on chemical, physical and structural properties of organic superconductors, since the discovery of the first organic superconductor (TMTSF)2PF6 by Jérome, Bechgaard et al. in 1980 [1]. As yet, they are not sufficient enough to yield a definitive picture of the mechanism of superconductivity, and to predict new organic superconductors. At present, more than 30 organic superconductors have been reported, and they have a maximum Tc (midpoint of resistance jump) in the range of 11. 0 – 11. 1 K (a Tc of 12. 8 K was recently observed in one single crystal). The total number of organic systems is still less than 1%, and the maximum Tc is less than 1/10 of those of inorganic systems (Fig. 1). It is an urgent task for chemists to explore a variety of new organic superconductors, and to extend Tc to the range of 15 – 20 K, at least.
