Electronic structure of conducting π-electron systems

Abstract

We will discuss the application of one-electron band theory to several systems where π-electron delocalization has been experimentally established. We will use polyacetylene as our prototype and extend results on it to related polymers such as (SN)x, polypyrrole and poly(p-phenylene). We will particularly concentrate on those aspects of chemical bonding and symmetry which govern whether a given system will be semiconducting or metallic, and which scale its transport properties. © 1980.
