This thesis divide into 2 part: The first part, we have successfully synthesized a series of indenopyridine -embedded oligomers, by using of selectively Suzuki coupling reaction, LDA cyclization reaction, Feiedel-Crafts alkylation. The promising optoelectronic properties, thermal stabilites of these materials and the UV-OLED of T2N were demonstrated. T2N can be also used as the host material for red and green phosphorescent dopants, the experimental results show very high external quantum efficiencies in the phosphorescent OLED. The second part, we have synthesized two novel series of triplet emitters, based on aryl-1,2,3-triazole and aryl-pyrimidine systems, the aryl-1,2,3-triazole ligand was synthesized via Sonogashira coupling reaction, click chemistry reaction. The aryl -pyrimidine ligand was synthesized via Suzuki coupling reaction. These ligands further react with IrCl3 to give corresponding triplet emitters. the experimental result shows, N-Firpic is a very good material in the phosphorescent OLED.
