Abstract
-
Recently, metal-organic compounds and organic polymers have attracted much attention for their potential applications involving organic light emitting diodes (LEDs). The visible radiation emitted by these organic LEDs can be tailored for several applications such as multicolor displays, computer backlighting, or computer display monitors. This thesis will consider the unique optical properties of the lanthanide-benzoylbenzoate complexes and use these properties to fabricate thermally stable LEDs with narrow spectral linewidths emitting in the red and green regions of the visible spectrum. These devices are constructed by combining the lanthanide-benzoylbenzoate complexes with suitable polymer matrices, compatible hole transport compounds or electron transport materials in single or multiple layer cell configurations. Organic polymers have already been synthesized for emission in the red, orange, yellow, green, and most recently, the blue region. However, thermally stable organic emitters are also important for developing reliable light emitting devices operating in the blue region. Poly(benzoyl,1-4,phenylene) (PBP), a soluble PPP-type polymer possessing very high thermal stability, was used to fabricate LEDs emitting (with high brightness) in the blue region of the spectrum. The results show that PBP is a promising candidate material for optoelectronic applications.
