Tuning the triplet energy transfer between a PMP and blue TPF2 iridium dopants leading to enhancement of OLED device performance |
| 초록 |
In this study, we prepared phenylimidazole-based C^N-cyclometalated Ir(III) complexes (DMP, TPF2) and C^C-cyclometalated Ir(III) complex (PMP) and investigated the energy transfer process through intermolecular interactions between the two cyclometalated Ir(III) complexes. In films doped with 3% Ir(C^C)3 complex (PMP) and 15% Ir(C^N)3 complex (DMP or TPF2), the PMP effectively induced energy transfer to the DMP or TPF2. This intermolecular energy transfer process was investigated using a picosecond time-resolved emission spectroscopic method. And we analyzed the energy transfer process when PMP was added to the dopant (TPF2, DMP) and confirmed that TPF2 was more efficient than DMP. Finally, it was confirmed that the operation lifetime and efficiency of the device was improved by doping 3% of PMP in EML. |
