以邻苯二胺和苯甲醛为原料,通过与三氯化铱配合,制得一种新型绿色磷光铱(Ⅲ)1-苯甲基-2-苯基苯并咪唑(bpbi)乙酰丙酮(acac)配合物(bpbi)_2Ir(acac)。通过质谱、核磁对其结构进行了表征,并对其光致发光性能进行了研究。研究结果表明:(bpbi)_2Ir(acac)在411和454nm处的可见光吸收属于单线态和三线态金属铱到配体的电荷越迁;在515nm处有强的绿色磷光发射;(bpbi)_2Ir(acac)的最高占据轨道(HOMO)为-4.59eV、最低空轨道(LUMO)为-1.01eV。(bpbi)_2Ir(acac)是一种极有潜力的电致磷光材料。
Using o-phenylenediamine and benzaldehyde as raw materials, a novel green phosphorescent iridium (Ⅲ) 1-benzyl-2-phenylbenzimidazole (acac ) Complex (bpbi) _2Ir (acac). Its structure was characterized by mass spectrometry and nuclear magnetic resonance, and its photoluminescence properties were studied. The results show that: (bpbi) _2Ir (acac) at 411 and 454nm visible light absorption belongs to the singlet state and triplet metal iridium to ligand charge more; 515nm at a strong green phosphorescence emission; (bpbi) _2Ir (acac) acac) has a HOMO of -4.59 eV and a LUMO of -1.01 eV. (bpbi) _2Ir (acac) is a very promising electro-phosphorescent material.
