1. Context

In the 1980s, the semiconductors used in electronic devices were all inorganic materials based on silicon, germanium, gallium arsenide, gallium nitride and so on. At the time, the term "organic material" referred to an "insulating material" not suitable for this type of application. The discovery and advent of conductive polymers in the 1970s-1990s, starting with the demonstration of electrical conductivity in polyacetylene films
