中文摘要：

与 1-phenylisoquinoline (1-piq ) 和 functionalized -diketone (G1 ) 协调的新 functionalized heteroleptic 铱建筑群，红外(1-piq ) 2G1，被 1H-NMR，集体 spectrometry 和元素的分析综合并且描绘。由 functionalized -diketonate ligand 的 acetylacetone (acac ) 的代替的更大的变化形式向真空水平在人水平导致了重要减少，当时红外(1-piq ) 2G1 和红外(1-piq )(acac ) 2 在 dichloromethane 显示出大约 620 nm 的红发磷光的排出物答案。发磷光的聚合物轻射出的设备被完成，搬运材料，当主人聚合物作为电子与 30%5-(4-biphenylyl ) 做了 -2-(4-tert-butylphenyl)-1,3,4-oxadiazole (PBD ) ，建筑群与 polyfluorene (PFO ) 合并了。设备的精力转移机制也被讨论。红外(1-piq ) 2G1 的更低的 EL 性能被归功于到 inter-ligand 精力转移，显示控制 cyclometalated 和辅助 ligands 的精力水平是重要的。

英文摘要：

A new functionalized heteroleptic iridium complex coordinated with 1-phenylisoquinoline （1-piq） and a functionalized fl-diketone （G1）, Ir（1-piq）2G1, was synthesized and characterized by 1H-NMR, mass spectrometry and elemental analysis. The larger conjugation of the replacement of acetylacetone （acac） by a functionalizedβ-diketonate ligand led to a significant decrease in the HOMO level toward vacuum level, while Ir（1-piq）2G1 and Ir（1-piq）2（acac） showed red phosphorescent emissions of about 620 nm in dichloromethane solution. The phosphorescent polymer light-emitting devices were achieved, with the complexes incorporated with polyfluorene （PFO） as a host polymer doped with 30% of 5-（4-biphenylyl）-2-（4-tert-butylphenyl）-1,3,4-oxadiazole （PBD） as electron transport material. The energy transfer mechanism of the devices was also discussed. The lower EL performance of Ir（1-piq）2G1 is ascribed to the inter-ligand energy transfer, indicating that it is important to control the energy level of the cyclometalated and ancillary ligands.
