Organic Metals and Semiconductors: The Chemistry of Polyacetylene, (CH)x, and Its Derivatives.

Abstract

Both cis- and trans-forms of polyacetylene, (CH)(x), may prepared as silvery, flexible polycrystalline, semiconducting films. The cis-films can be stretched to over three times their original length with partial alignment of the (CH)(x) fibrils. Through chemical or electrochemical doping, the electrical conductivity of the films can be increased over twelve orders of magnitude with properties ranging from insulator to semiconductor to metal. By the use of donors or acceptors, n-type or p-type polymer, respectively, is produced. Photoelectrochemical photovoltaic cells have been fabricated using (CH)(x) as the active photoelectrode.
