Synthesis of Trifluorosulfonyl Substituted Iridium Complexes for Blue Phosphorescence |
| 초록 |
For color-pure phosphorescence organic light emitting diodes, we synthesized the trifluoromethyl sulfonyl substituted ligand and SOCF3pic and SOCF3mpic as two new blue Iridium complexes. The SOCF3pic and SOCF3mpic complexes exhibited identical photophysical and thermal stabilities while the HOMO energy levels of two Iridium complexes slightly dissimilar to be −5.84 eV for SOCF3pic and −5.74 eV for SOCF3mpic, each material. The device with the SOCF3mpic dopant showed higher device efficiencies of 7.17 cd/A and 3.7% compared to that with the SOCF3pic dopant (4.03 cd/A and 2.78%). Two-dimensional GIXD picture of be dotted X-ray intensity from surface to full depth for SOCF3pic-doped and SOCF3mpic-doped TCTA:4PTPS films were distinct featured for preferential orientation along the out-of-plane direction. |
