Polyaniline

Space-filling model of the local structure of a polyaniline chain in the reduced leucoemeraldine base (LEB) oxidation state, based on the crystal structure of the tetramer.

Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. The compound has been of interest since the 1980s because of unique electrical and mechanical properties. Polyaniline is one of the most studied conducting polymers.
