Abstract
Attempts to obtain high critical temperature superconductors by means of organic or related superconductor models are reviewed. These attempts may be classified into five types: (1) Little's model and its modification (2) Ginzburg's model and its modification (3) Perlstein's model and its modification (4) attempts based upon electrically conductive polymers (5) attempts by means of biochemical preparation. None of them have yet been successful, but in many respects progress is being made. These attempts seem to try to find new mechanisms for synthesizing superconductors, e.g. the exciton mechanism, which differ from the already known phonon-electron interaction machanism.
