Abstract

The class of solids known as organic charge transfer salts has received considerable attention in recent years. This interest arises from the novelty of the systems as well as from the fact that the flat planar molecules involved lead to anisotropic structures and therefore to pseudo one-dimensional electronic properties. The existence of real physical systems1–3 which have the properties of one-dimensional metals is particularly important because of the exciting possibilities associated with the one-dimensional electron gas.4–10 The pseudo one-dimensionality of the electronic properties of tetrathiofulvalinium tetracyanoquinodimethan (TTF-TCNQ) has been established experimentally by a variety of measurements.3,11–15 As a highly conducting organic metal which remains metallic to relatively low temperatures,11, 15, 16 this system is at the focus of work directed toward understanding the nature of the metallic state in pseudo one-dimensional conductors. More generally, the existence of a class of materials made up of organic molecules as fundamental units allows the possibility of utilizing the flexibility of organic chemistry to design and synthesize molecules with particular characteristics with the intent of achieving a desired bulk solid state property.

    Several groups have carried out studies of the crystal structure at and below room temperature. As of this writing, no extra lines (indicative of a change in unit cell) have been observed. This work is continuing. We note, however, that one must be careful not to draw permature conclusions since the low z atoms involved are weak scatterers and, especially if 2kF is incommensurate with the lattice, the corresponding superlattice lines might be extremely weak.Google Scholar
