Description

Organic compounds, mixtures, compositions and uses thereof
The present application claims priority of the chinese patent application with application number 201911202496.X entitled "a pyrenequinone organic compound and its use" filed in 2019, 11, 29, month, the entire contents of which are incorporated herein by reference.
Technical Field
The invention relates to the technical field of organic electroluminescence, in particular to an organic compound, a mixture, a composition and application thereof.
Background
Organic Light Emitting Diodes (OLEDs) have great potential for applications in optoelectronic devices, such as flat panel displays and lighting, due to their advantages of being versatile, low cost to manufacture, and good in optical and electrical performance.
The organic light emitting diode consists of three parts, namely an anode, a cathode and an organic layer between the anode and the cathode. In order to improve the efficiency and lifetime of the organic light emitting diode, the organic layer generally has a multi-layer structure, and each layer contains different organic substances. Specifically, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, and the like may be included. The basic principle of the light emission of the organic light emitting diode is as follows: when a voltage is applied between the two electrodes, the positive electrode injects holes into the organic layer, the negative electrode injects electrons into the organic layer, and the injected holes and electrons meet to form excitons, which emit light when they transition back to the ground state. The organic light emitting diode has the advantages of self-luminescence, high brightness, high efficiency, low driving voltage, wide viewing angle, high contrast, high responsiveness and the like. In order to improve the recombination efficiency of the injected holes and electrons, further improvement in the structure, material, and the like of the organic light emitting diode is required.
Currently, merck company utilizes aromatic diamine derivatives or aromatic fused ring diamine derivatives as hole transport materials of organic light emitting diodes to improve the efficiency of injecting holes, but at this time, the organic light emitting diodes can fully emit light by increasing the use voltage, which leads to the problems of reduced service life and increased power consumption of the organic light emitting diodes.
Such problems have recently been solved by doping the hole transport layer of organic light emitting diodes with electron acceptors, such as Tetracyanoquinodimethane (TCNQ) or 2,3,5, 6-tetrafluoro-tetracyano-1, 4-benzoquinodimethane (F4TCNQ) (Chemical Science 2018,9(19), 4468-: the operation is unstable in the manufacturing process of the organic light emitting diode, the stability is insufficient when the organic light emitting diode is driven, the life is reduced, or the above compound is diffused in the device to contaminate the device when the organic light emitting diode is manufactured by vacuum deposition.
Therefore, there is a need for further improvement of an electron acceptor, i.e., a P-dopant, doped in the hole transport layer, particularly a dopant that can realize a low voltage and a long lifetime of the organic light emitting diode.

In the embodiment of the present invention, the energy level structure of the organic material, the triplet state energy level ETHOMO, LUMO play a key role. The determination of these energy levels is described below.
The HOMO and LUMO energy levels can be measured by the photoelectric effect, for example XPS (X-ray photoelectron spectroscopy) and UPS (ultraviolet photoelectron spectroscopy) or by cyclic voltammetry (hereinafter referred to as CV). Recently, quantum chemical methods, such as the density functional theory (hereinafter abbreviated as DFT), have become effective methods for calculating the molecular orbital level.
Triplet energy level E of organic materialT1Can be measured by low temperature Time resolved luminescence spectroscopy, or can be obtained by quantum simulation calculations (e.g., by Time-dependent DFT), such as by commercial software Gaussian 03W (Gaussian Inc.), specific simulation methods can be found in WO2011141110 or as described in the examples below.
Note that HOMO, LUMO, ET1The absolute value of (c) depends on the measurement method or calculation method used, and even for the same method, different methods of evaluation, for example starting point and peak point on the CV curve, can give different HOMO/LUMO values. Thus, a reasonably meaningful comparison should be made with the same measurement method and the same evaluation method. In the description of the embodiments of the present invention, HOMO, LUMO, ET1Is based on the simulation of the Time-dependent DFT but does not affect the application of other measurement or calculation methods.
In the present invention, (HOMO-1) is defined as the second highest occupied orbital level, (HOMO-2) is defined as the third highest occupied orbital level, and so on. (LUMO +1) is defined as the second lowest unoccupied orbital level, (LUMO +2) is the third lowest occupied orbital level, and so on.
