  Synthesis and luminescence study of red phosphorescent Ir(III) pyrazolonate complexes for OLED

  摘要：

  A pyrazolone-based ligand, 4-acetyl-5-methyl-2-phenyl-2,4-dihydro-pyrazol-3-one (pyzl), was prepared and introduced as a new ancillary ligand, replacing acac in the iridium complexes for high efficient OLED. The purpose of this study was that modification of the ancillary ligand might allow luminous efficiency increase by reducing T-T annihilation. The przl ligand in the iridium complex might also lead to fine tuning of the emission color by affecting the energy level of Ir d-orbitals. Previously, we reported that the iridium complexes, Ir(4-Me-2,3-dpq)(2)(acac) and Ir(2,3-dpqx-F-2)(2)(acac), exhibited their electroluminescence (EL) emission at 603 and 630 nm with luminous efficiency of 8.10 and 2.75 cd/A, respectively, where 6-Me-2,3-dpq, 2,3-dpqx-F-2 and acac represent 4-methyl-2,3-diphenylquinoline and 2,3-bis-(4-fluorophenyl)quinoxaline and acetylacetonate, respectively. In this study, we synthesized a new series of iridium complexes with the pyrazolonate ligand, Ir(6-Me-2,3-dpq)2(przl) and Ir(2,3-dpqx-F2)2(przl), and investigated their luminescence properties with respect to the involvement of a new bulky ancillary ligand, przl, compared with the complexes containing the ligand acac.

  New types of heteroleptic iridium complexes were designed and synthesized with two different species of chelating ligands (C boolean AND N) in this study. Ir(ppy)(2)(4-Me-2,3-dpq), Ir(ppy)(4-Me-2,3-dpq)(2), Ir(pq)(2)(4-Me-2,3-dpq) and Ir(pq)(4-Me-2,3-dpq)(2) were prepared, where ppy, 4-Me-2,3-dpq and pq represent 2-phenylpyridine, 4-methyl-2,3-diphenylquinoline and 2-phenylquinoline, respectively. According to our previous study, Ir(4-Me-2,3-dpq)(2)(acac) showed orange-red emission at 603 nm with the luminescence efficiency of 8.10 cd/A in electroluminescence (EL) spectra. On the otherhand, Ir(ppy)(2)(acac), a green phosphor, has been known to have an outstanding efficiency of more than 45 cd/A. In order to improve the luminescence efficiency, it is necessary to design a phosphorescent material which is capable of transferring the excited energy efficiently and properly. The heteroleptic Ir(III) complexes containing two different kinds of ligands can have a high luminescence efficiency by intramolecular energy transfer from the energy-absorbing ligand to the luminescent ligand, leading to a decrease in quenching or energy deactivation. Thus, the luminescence characteristics of the iridium, complexes prepared herein were investigated. Ir(ppy)(2)(4-Me-2,3-dpq), Ir(ppy)(4-Me-2,3-dpq)(2), Ir(pq)(2)(4-Me-2,3-dpq) and Ir(pq)(4-Me-2,3-dpq)(2) exhibited the emission maxima at 512, 512, 583, and 584 nm, respectively. Two different light-emitting mechanisms were suggested to explain these phenomena. (C) 2007 Elsevier Ltd. All rights reserved.
