Description
Technical field
The present invention relates to organic electroluminescence device technical field, a kind of hole transport layer material has higher
Triplet T1 and the organic electroluminescence device of mobility.
Background technology
The luminescent layer of organic electroluminescent device OLED mainly use full fluorescent material, full phosphor material or fluorescent material and
The mode of phosphor material mixing makes.Owing to blue and green light, red device are different, especially to the requirement of hole transmission layer HTL
It is green glow and HONGGUANG to have high triplet T1 to HTL material, but has the HTL material of high triplet T1
Material, the most all has low mobility, and driving voltage is high, and the life-span is short, so for the performance pair meeting RGB device simultaneously
HTL material should have high T1 to have high mobility, current this kind of material to be difficult to find again.
In OLED display device preparation process, in order to reduce technology difficulty and production cost, the accurate mask of general employing
The respectively luminescent layer of vacuum evaporation red, green, blue sub-pixel, and hole injection layer outside luminescent layer, hole transmission layer, electronics pass
The shared unified evaporation film-formings such as defeated layer, hole/exciton barrier-layer.The phosphorescent coloring used due to red and green subpixels luminescent layer
Triplet excitons last a long time, easily diffuse to electron transfer layer, cause Exciton quenching to inactivate, therefore at luminescent layer and electronics
One layer of exciton barrier-layer (HBL) is set between transport layer.Exciton barrier-layer material typically requires have higher triplet
And higher HOMO energy level, thus stop that triplet excitons enters electron transfer layer.
Samsung discloses a kind of electroluminescent device 201210395191.7, as it is shown in figure 1, it is in the following order
Comprise successively substrate the 110, first electrode 120, hole injection layer 130, hole transmission layer 140, cushion 150, luminescent layer 160,
