摘　　要：以苊为原料合成5-苊甲醛,分别与邻氨基苯硫酚、邻氨基苯酚、邻苯二胺缩合得到5-（2-苯并噻唑）苊、5-（2-苯并噁唑）苊、5-（2-苯并咪唑）苊3种配体,分别与三氯化铱反应得到相应的铱配合物.配体在400 nm之后没有吸收,与金属铱配位后,400 nm之后出现新吸收峰.配体发蓝色光,波长范围360-420 m;铱配合物发橙色-红色光,波长范围560-660 nm.与配体发射峰400 nm左右相比,铱配合物发射峰红移至600 nm左右,有望作为一种新型的橙红色染料应用到有机电致发光器件中.5-acenaphthene carbaldehyde is synthesized by the oxidation of acenaphthene. Its condensation with 2-aminothiophenol,2-aminophenol,and 2-amino-aniline, can afford three acenaphene derivatives ligands. In the reaction with iridium trichloride three iridium complexes are produced containing acenaphthene derivatives ligands. The three ligands have peak absorption at 330 - 350 nm,while the peak absorption of the iridium complexes is at about 400 - 500 nm in the THF solutions. The derivatives emit blue luminescence with the emission peak at 360 - 420 nm and the complexes have orange-red luminescence with fluorescence peak at 560 - 660 nm. Compared to the emission peak of the ligands about 400 nm, the complexes red-shifting to around 600nm, making novel red luminescent materials in organic light-emitting diodes（OLEDs）.
