摘要:

合成了一类自主体蓝绿色磷光铱(Ⅲ)配合物(CzPhBI)2Ir(tfmptz), (CzPhBI)2Ir(tfmpptz)和(CzPhBI)2Ir(fpptz)[其中CzPhBI, tfmptz, tfmpptz和fpptz分别为9-[6-(2-苯基-1-苯并咪唑基)己基]-9-咔唑、 2-(5-三氟甲基-1,2,4-三唑基)吡啶、 2-(5-[4-(三氟甲基)苯基]-1,2,3-三唑)吡啶和2-[5-(4-氟苯基)-1,2,3-三唑]吡啶]. 通过核磁共振氢谱和氟谱及元素分析确定其分子结构, 并对其光物理性能进行了研究. 利用该类配合物作为单发光层制备了器件结构为氧化铟锡(ITO)│N,N'-二苯基-N,N'-二(1-萘基)-1,1'-联苯-4,4'-二胺(NPB)(30 nm)│4,4'-N,N'-二咔唑基联苯(CBP)(15 nm)│Ir配合物(30 nm)│1,3,5-三(1-苯基-1H-苯并咪唑-2-基)苯(TBPI)(30 nm)│LiF(1 nm)│Al(100 nm)的电致发光器件, 其最大亮度为6913 cd/m2, 最大发光效率达13.9 cd/A.

Abstract:

A kind of self-host blue-green phosphorescent Ir(Ⅲ) complexes [(CzPhBI)2Ir(tfmptz), (CzPhBI)2Ir(tfmpptz) and (CzPhBI)2Ir(fpptz)] was designed and synthesized. CzPhBI, tfmptz, tfmpptz and fpptz were 9-[6-(2-phenyl-1-benzimidazolyl)hexyl]-9-carbazole, 2-(5-trifluoromethyl-1,2,4-triazolyl)pyridine, 2-[5-(4-trifluoromethyl)phenyl-1,2,4-triazolyl]pyridine and 2-[5-(4-fluoro)phenyl-1,2,4-triazolyl]pyridine, respectively. The structures were confirmed by nuclear magnetic resonance(1H NMR and 19F NMR) and elemental analysis. Photophysical properties were investigated. Electroluminescent performance of Ir(Ⅲ) complexes were characterized by fabricating the non-doped devices with the configuration of indium tin oxid(ITO)│N,N'-bis-(1-naphthalenyl)-N,N'-bis-phenyl-(1,1'-biphenyl)-4,4'-diamine(NPB)(30 nm)│4,4'-Bis(9-carbazolyl)-1,1'-biphenyl(CBP)(15 nm)│Ir complexes(30 nm)│1,3,5-tris(1-phenyl-1H-benzo[d]imidazol-2-yl)benzene(TBPI)(30 nm)│LiF(1 nm)│Al(100 nm). The maximum luminance of (CzPhBI)2Ir(tfmpptz) complexes was 6913 cd/m2 and the maximum luminous efficiency achieved 13.9 cd/A.
