The three band Hubbard modal with nearest neighbour repulsion is studied in the U = c~ limit using the slave boson technique and the large N expansion. A charge transfer (CT) instability is found like ill weak coupling theory. The CT instability is always associated with a divergin 8 compressibility

The organic superconductors now have eight year history. The first generation (TMTSF)2X is characterized by the quasi one-dimensionality and the competition with SDW. Novel superconductivity mechanisms via the intramolecular vibration and by the anisotropic coupling have been argued. The BEDT-TTF sa
