Luminescent polymer LEDs: an overview

The advent of organic materials for electroluminescent devices has allowed a wide variety of applications in displays, communications, sensors, and the like. This paper gives an overview of this search past, present, and future and the synthesis of promising new complex polymer building blocks which can yield electro-luminescent light emitting diode (LED) devices for displays, and communications. Methods and materials of fabrication are discussed, and test results are interpreted in the light of previous theory and device structure measurements. Device operation, in several configurations and colors, over a wide temperature range, is discussed.
