Description
Technical Field
The present invention relates to an organic compound and an organic light emitting tube device using the same, and more particularly, to a soluble organic compound having excellent color purity and high luminance and high light emitting efficiency and an OLED device using the same.
Background
With the development of multimedia technology and the increase of information-oriented requirements, the requirements for the performance of panel displays are increasing. The OLED has a series of advantages of autonomous light emission, low-voltage direct current driving, full curing, wide viewing angle, rich colors and the like, is widely noticed due to potential application in new-generation displays and lighting technologies, and has a very wide application prospect. The organic electroluminescent device is a spontaneous light emitting device, and the OLED light emitting mechanism is that under the action of an external electric field, electrons and holes are respectively injected from a positive electrode and a negative electrode and then migrate, recombine and attenuate in an organic material to generate light. A typical structure of an OLED comprises one or more functional layers of a cathode layer, an anode layer, an electron injection layer, an electron transport layer, a hole blocking layer, a hole transport layer, a hole injection layer and an organic light emitting layer.
Although the research on organic electroluminescence is rapidly progressing, there are still many problems to be solved, such as the improvement of External Quantum Efficiency (EQE), the design and synthesis of new materials with higher color purity, the efficient electron transport, the design and synthesis of new hole blocking materials, and the like. For the organic electroluminescent device, the luminous quantum efficiency of the device is the comprehensive reflection of various factors and is an important index for measuring the quality of the device.
Luminescence can be divided into fluorescence and phosphorescence. In fluorescence emission, an organic molecule in a singlet excited state transits to a ground state, thereby emitting light. On the other hand, in phosphorescence, organic molecules in a triplet excited state transition to a ground state, thereby emitting light.
At present, some organic electroluminescent materials have been commercially used due to their excellent properties, but as host materials in organic electroluminescent devices, it is more important to have good hole transport properties in addition to the triplet energy level higher than that of the guest materials to prevent the energy reverse transfer of exciton transition release. Currently, materials having both a high triplet level and good hole mobility in the host material are still lacking. Therefore, how to design a new host material with better performance is a problem to be solved by those skilled in the art.
