Some molecular systems for a charge‐mediated superconductor are proposed from the viewpoint of the metallic side and the insulator side. An approach to the charge‐transfer (CT) model is presented. Expressions of the effective electron–electron interaction in the charge‐fluctuation models is also derived by a field‐theoretical approach. © 1998 John Wiley & Sons, Inc.
