Recent progress in the development of polymers for white light-emitting polymer devices

Much effort has been devoted to the design and synthesis of polymers for use in flat panel display, solid state lighting, transistors, and photovoltaic devices. Especially, development of white light emitting polymeric materials has recently attracted much interest owing to their possible use in lighting application and backlights for flat panel displays. White emission has been obtained from polymeric molecules, small organic molecules, organometallic molecules, and phosphor-based or quantum dot-based inorganic molecules. Among materials used in white light emitting diodes, we summarize the white light emitting polymeric materials synthesized and published till December 2007.
