Summary:The discovery of extraordinary conductivity maxima in a class of organic charge transfer salts is reported. The data are interpreted as resulting from superconducting fluctuations at high temperatures. A possible mechanism for achieving high temperature superconductivity is suggested based on the electron-phonon interaction, in the strong-coupling limit, and the Peierls soft-mode instability in pseudo-one-dimensional systems. Procedures are suggested for the possible eventual stabilization of the superconducting state. La découverte des maximas extraordinaires de conductivité dans une classe de sels chargés transferés est rapportée. Les données sont interpretées comme résultats des fluctuations supraconductivantes à haut temperature. On suggère un mécanisme possible pour achever la superconductivité à haut temperature, fondée sur l'intéraction électron-phonon, dans la limite d'accouplement fort, et sur l'instabilité de la mode douce de Peierls dans les systèmes pseudo-uni-dimensionnelles. On propose des méthodes pour la stabilisation possible et éventuelle de l'état supraconductivant.
