Novel polymers for light emitting diodes [PDF Document]
Light emitting polymers Oled Liquid Crystal Display. A series of saturated red emission copolymers, polyfluorene copolymers (PFO-DBT), were synthesized and characterized. The saturated red EL emission from the copolymer peaking at about 677 nm and electroluminescence (EL) efficiency of 1.4% based on simple device structure of ITO/PEDOT/PFO-DBT/Ba/Al, were achieved., A series of novel blue light-emitting polymers were designed and synthesized by incorporating a blue styrylarylene amine (DV) chromophore into the backbone of poly(9,9-dioctylfluorene)..

An experimental survey of the optical properties of the phenyl-based light emitting polymers (poly (para-phenylene) and poly (para-phenylene vinylene)) is given. These are then explained by developing a theoretical model of their excited states via a discussion of the excited states of benzene, biphenyl, stilbene and oligophenylenes. Results of 5/02/2011 · Organic light emitting diode (OLED) display technology has been grabbing headlines in recent years. Now one form of OLED displays, LIGHT EMITTING POLYMER (LEP) technology is rapidly emerging as a serious candidate for next generation flat panel displays.
