Organic Superconductivity: The First Quarter Century

  • W. A. Little


This, the International Conference on Organic Superconductors commemorates the twenty-first anniversary of the first such Conference1 which was held in the Fall of 1969, in Honolulu. The intent of that meeting was to bring together theoretical and experimental physicists, and theoretical, organic and inorganic chemists, and introduce them to the challenge of designing and synthesizing polymeric, organic compounds which would superconduct at high temperatures2. That conference served to catalyze work in this area and within the next decade the first 2D-superconductors intercalated with organic compounds were prepared3; the first polymeric superconductor was synthesized4 in 1975; and, in 1980, the first organic superconductor was discovered5. Much progress has been made since then6, with more than thirty organic superconductors now known, and some with transition temperatures as high as 11K. On the other hand, during this period, the search for high temperature superconductivity appeared more elusive, with little progress made until the discoveries7 of the high Tc cuprates in 1986. These discoveries have established the validity of the early arguments that such high transition temperatures were possible, although the exact8 mechanism responsible for the superconductivity in these materials has not yet been fully identified. They have provided encouragement for the study of non-conventional conducting materials including such materials as the oxides and the organics. The latter continue to offer a rational route to the synthesis of compounds which may yet yield materials with transition temperatures comparable to, or higher, than those of the cuprates.
