摘要

Molecular crystalline solids based on organic and organometallic componentsexhibit numerous electronic phenomena, including electrical conductivity, superconductivity, nonlinear optical behavior, and ferromagnetism. The most extensively examined molecular crystals have been the low-dimensional conductors, which generally exhibit anisotropic conductivity along axes containing stacks of open-shell charge-transfer molecules that are responsible for the formation of extended band structure. Most notable among these are the organic superconductors. While the superconductivity critical temperatures are lower than those of oxide superconductors or the recently discovered superconducting phases of alkali-metal-doped C60, these materials present an opportunity to examine structure-function relationships of extended solids. The principal advantage of molecular materials is the ability to rationally control bulk properties through molecular design.
