摘要 两个含有载流子β-二酮配体的新型铱配合物被成功合成。分别为Ir(L)2(acac-Ox)和Ir(L)2(acac-Cz)。其中L=3-(2-吡啶)香豆素环金属铱配合物,acac-Ox=3-(4-(5-(4'-叔丁基苯基)-1,3,4-噁二唑)苄基)-戊二酮,acac-Cz=3-((4-(9-咔唑-)苯基)甲基)戊烷-2,4-戊二酮,并且通过了核磁,紫外等数据分析。配合物的光物理性质采用紫外-可见,光致发光光谱分析研究。配合物acac-Cz做成的器件,在9%的参杂浓度下器件的发光效率效果最佳。配合物acac-Ox当参杂浓度为6%时,器件的发光效率最佳。通过对器件发光性能的比较,acac-Cz通过引入咔唑空穴传输基团提高了器件的性能。它们都是很好的绿光发光材料。 Two new iridium complexes containing carrier β-diketone ligands were successfully synthesized , namely Ir(L)2(acac-Ox) and Ir(L)2(acac-Cz), in which L=3-(pyridin-2-yl)coumarinatoringmetaliridiumcomplexes , acac-Ox=3-(4-(5-(4′-tertbutylphenyl) -1,3,4-oxadiazole)benzyl) -pentane-2,4-dionateandacac -Cz=3-((4 -(9H -carbazol -9 -yl) phenyl) methyl) pentane -2,4 -dionate, and were successfully synthesized and characterized by elemental analysis , 1 H NMR and FT-IR.Photophysical properties of complexes using UV -visible , photoluminescence spectroscopy were studied.The devices based on Ir ( L ) 2 ( acac -Cz ) with 9%(ω) doping concentration showed the best EL efficiency performance , and emits green light.The devices based on Ir(L)2(acac-Ox) with 6%(ω) doping concentration showed the best EL efficiency performance acac -Cz by introducing a carbazolyl group to improve the hole transport properties of the device.
