Summary

This course provides an introduction to organic semiconducting materials starting from fundamental optical and electronic properties of small conjugated molecules and polymers. Electronic and optical solid sate properties and applications in organic and hybrid optoelectronic devices are studied.

Content

1. Conjugated molecules interacting with light (electronic orbitals, optical and electronic properties, photochemical reactions), biological systems
2. Structure and properties of conjugated molecular materials (crystalline materials, polymers, liquid crystals)
3. Applications in electronics and optoelectronics (LCD displays, solar cells, light-emitting diodes, transistors)

Keywords

Organic conjugated molecules, conjugated polymers, molecular orbitals, fluorescence, phosphorescence, energy transfer, electron transport, electronic and optoelectronic devices, hybrid organic-inorganic devices
