Organic conducting and semiconducting materials based on ⺎-conjugated systems or organic/inorganic hybrid materials have become essential components in the field of low-cost flexible electronics. They are used in three key technological areas with very high industrial development potential: organic light-emitting diodes for lighting and displays, organic field-effect transistors and photovoltaic cells. The main objectives of this course are to:
i) present these classes of organic and organic/inorganic hybrid materials, their properties and their characterization methods,
ii) establish structure / property relationships and
iii) describe the operating principle of electronic components incorporating such materials as well as the laws that govern their efficiencies.

The physical methods used for the characterization of the performance of these devices will also be introduced in order to give a global vision of their design, manufacturing and evaluation. Although this course does not intend to dwell on synthesis of ⺎-conjugated systems, a specific attention will be paid to the chemical and electrochemical synthesis of polymers for electronic organics as well as their application in the fields of electro-chemical and optical sensors, transparent conducting or electrochromic materials.
