Bulk and interface degradation processes in polymer electroluminescent devices

Recently, there has been increasing interest in applications of polymeric materials in electro-optic devices. Electroluminescent polymers constitute a particularly promising application. Over the course of the last five years, several groups around the world have demonstrated the great flexibility of these materials in producing light-emitting devices that are easy to assemble, are relatively efficient, and produce light across the full visible spectrum . 1'7 Many envision these polymers revolutionizing the field o f light-emitting diodes (LEDs), which is currently dominated by inorganic semiconductors. Polymers offer the opportunity to produce lightweight, large area, full color display devices that can be built on flexible substrates that roll up when not in use .8 Significant progress has been made to synthesize polymers that are more efficient, easier to process, and are compatible with flexible polymeric substrates.9
