Organic Electronic Devices Based on Polymeric Material and Tunable Photonic Crystal

The historical background and recent progress in the development of organic electronics and photonic crystals, particularly tunable photonic crystals realized by combining photonic crystal structure with functional organic molecules, are discussed. The novel characteristics of organic electronic devices with mainly conducting polymers, which are related to the optical effects, and the tunable photonic crystals composed of periodic structures of optical wavelength order combined with functional organic materials are demonstrated.
