英文摘要合成了4种吡嗪铱配合物,用质谱和1 H NMR对配合物结构进行了表征,通过紫外-可见吸收光谱和光致发光光谱对其光物理性质进行了研究。结果表明:4种铱配合物都出现了金属-配体电荷转移( MLCT )吸收峰。铱配合物1[(DFMPPZ)2Ir(pic)]、2[(DFMPPZ)2IrCl(PPh3)]、3[(DFMPPZ)2Ir(CN)(PPh3)]和4[(DPPF)2Ir(acac)]的发射波长分别为528,536,535,561 nm,都是潜在的黄、绿色磷光材料。以铱配合物4为客体材料,制备了结构为ITO/MoO3(1 nm)/CBP(35 nm)/CBP∶Ir(15 nm)/TPBi(50 nm)/LiF(1nm)/Al (100 nm)的一系列不同掺杂浓度的器件,器件的发射波长为567 nm,最大亮度达到32110 cd·m-2,最大电流效率为32.4 cd·A-1,最大功率效率为28.2 lm·W-1。; Four iridium (Ⅲ) pyrazine complexes 1 [(DFMPPZ)2Ir(pic)], 2 [(DFMPPZ)2IrCl-(PPh3)],3 [(DFMPPZ)2Ir(CN)(PPh3)], and 4 [(DPPF)2Ir(acac)] were synthesized, where DFMPPZ= 2-(2,4-difluorophenyl)-3-methylpyrazine, pic=picolinate, Ph=phenyl, acac=acetylaceto-nate, MDPPF=4,4'-difluoro-5-methyl-2,3-diphenylpyrazine. The complexes were characterized by mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. Their photophysical properties were investigated by UV-Vis and photoluminescence (PL) spectroscopy. All of these Ir (Ⅲ) complexes show the noticeable absorption peaks from metal-to-ligand charge transfer (MLCT) transitions. The iridi-um (Ⅲ) complexes 1, 2, 3 and 4 have strong photoluminescence at 528, 536, 535 and 561 nm, respec-tively. Moreover, the iridium (Ⅲ) complex 4 was utilized as phosphorescence dopant in OLEDs with the structures of ITO/MoO3(1 nm)/CBP(35 nm)/CBP∶Ir(15 nm)/TPBi(50 nm)/LiF(1nm)/Al(100 nm). The devices showed yellow emission at 567 nm with a maximum brightness of 32 110 cd·m-2 , current efficiency of 32. 4 cd·A-1 , and power efficiency of 28. 2 lm·W-1 .; 国家自然科学基金; 宁波大学学科项目; 宁波大学王宽诚基金; EI; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 3; 280-285; 37
