4. Conclusion

Because of their semiconducting and optical properties, their flexibility in terms of molecular engineering, the development of efficient synthesis routes, and their easy, low-cost processing, conjugated polymers and more generally conjugated materials have opened up the field of organic electronics. These materials make it possible to manufacture electronic components (e.g. organic light-emitting diodes, transistors, photovoltaic cells or sensors) on both rigid and flexible substrates.

From an industrial point of view, the field of display and lighting is now mature. The base materials for electron and hole injector layers, electron and hole transporters, emitters, etc., are produced by or in partnership with chemical groups such as Solvay (Belgium), Merck (Germany) and Sumitomo Chemicals (Japan). For example, Merck is developing the Livilux® range. Further downstream,...
