Composites of tin dioxide (an n-type semiconductor) and derivatives of the conducting polymer polypyrrole (a p-type semiconductor) gave reversible changes in electrical resistance at room temperature when exposed to a range of organic vapours. The op... Read More about Novel composite organic-inorganic semiconductor sensors for the quantitative detection of target organic vapours.

Application of density functional theory in the synthesis of electroactive polymers (1995)
Journal Article

Journal of the Chemical Society, Faraday Transactions, 91(15), 2331-2338. https://doi.org/10.1039/FT9959102331

A wide range of conjugated organic compounds undergo anodic electropolymerisation to produce polymers of high conductivity. However, electrooxidation does not always result in the formation of electroactive materials, since some reactions produce ins...
