We suggest that superconductivity (SC) in the organic charge-transfer solids (CTS) is reached from a bond-charge density wave (BCDW). We discuss an effective model for the BCDW to SC transition, an attractive U extended Hubbard Hamiltonian with repulsive nearest neighbor interaction V. We discuss experimental consequences of the theory for different classes of CTS superconductors as well as related inorganic materials. © 2008 Elsevier B.V. All rights reserved.
