Abstract
Organic light-emitting diodes(OLEDs) have received considerable attention since they were first reported by Tang. Novel organic fluorescent materials have been reported on synthesis and application of new organic light-emitting materials. Despite of much recent progress, fabrication of full-color OLEDs still remained to be done. Many method have been proposed to full-color OLEDs displays such as using separated red, green and blue emitters, stacking separate rad, green and blue emitter, using a white emitter with individually pattered color filters, microcavity structures and using a blue emitter with individually patterned fluorescent materials. The last method has much attention because of easy fabrication of OLEDs and low-priced fabrication. This paper reports the optical and electrical characteristics of OLEDs using novel molecules containing biphenyl structure. Optical properties of biphenyl derivatives doped with poly(9-vinyl carbazole)(PVK) are measured and found Forster energy transfer process in the blends. And devices were fabricated as ITO/PEDOT/PVK doped with biphenyl derivatives/
