Light emitting polymers respond to an electrical current by giving off visible radiation and they can be made into thin films or sheets. Light emitting polymers can also be called polymer LED, which LED stands for light-emitting diode, or polyLED and is a technology based on the use of polymer as the semiconductor material in LEDs. Polmers are chemical substances that consist of large molecules that are, themselves, made from many smaller and simpler molecules. Proteins and DNA are examples of naturally occurring polymers and nylon is an example of an artificially created polymer.1,2,3
Light emitting polymers belong to a special class of polymers called conjugated polymers. Conjugated polymers consist of carbon backbones with alternating single and double bonds and have shown great potential as light-emitting material. These polymers posses delocalized pi-electrons along the backbone. In the sense of mobility of delocalized pi-electrons, LEPs show the potential ......
