✦ Synopsis

We explain the phase diagram of the metal-insulator transition observed in a family of organic salts called DCNQI-Cu, assuming phenomenological free energies for the metallic and insulating phases. We point out that the heavy-electron mass is essential for the observed occurrence of the metal-insulator-metal reentrance.

We investigate the metal insulator transition of quasi-one dimensional organic conductors (DCNQI)2Cu by slave boson method. Within mean field approximation, we find that three interactions are needed for these organic conductors getting into insulator phase. These are an on-site Coulomb repulsion on
