Triazine based bipolar host materials for blue phosphorescent OLEDs

Two novel bipolar host materials BPTRZ and MBPTRZ were synthesized, in which the hole transporting carbazole is separated from the electron transporting triazine moiety by a fully aromatic, but nonconjugated meta-linked biphenyl unit. The additional twist at the biphenyl in MBPTRZ, which is achieved by methyl-substitution in 2- and 2′-position of the biphenyl leads to a higher triplet energy of 2.81 eV compared to 2.70 eV for BPTRZ. Both materials possess high thermal stabilities and good glass forming properties. An organic light emitting diode with MBPTRZ as host for the blue phosphorescence emitter FIrpic shows a maximum luminance of 30600 cd/m2 and a maximum external quantum efficiency of 7.0%.

High-efficiency electron blocking material and organic electroluminescence device using same

The invention discloses a high-efficiency electron blocking material and an organic electroluminescence device using the same. The structural formula is shown as a formula I in the specification. By using the high-efficiency electron blocking material, carriers and excitons are limited in a luminescent layer, electron escape and exciton diffusion can be effectively eliminated, so that the externalquantum efficiency is improved, and the service life of a device is further prolonged. According to an organic electroluminescence device prepared from the high-efficiency electron blocking layer material, the driving voltage is greatly reduced, the consumption of electric energy is greatly reduced, and the luminous efficiency is remarkably improved. In addition, by reducing the driving voltage,the service life of the organic electroluminescence device is remarkably prolonged.
