摘要：

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. (c) 2008 Elsevier B.V. All rights reserved.
