In recent years, optoelectronic devices based on organic materials have become increasingly popular. The inherent flexibility of organic materials makes them well suited for fabrication on flexible substrates, allowing for the design and production of aesthetically pleasing and crunchy optoelectronic products, with unparalleled advantages over inorganic materials. Examples of such organic optoelectronic devices include Organic Light Emitting Diodes (OLEDs), organic field effect transistors, organic photovoltaic cells, organic sensors, and the like. Among them, OLEDs have been developed particularly rapidly, and have been commercially successful in the field of information display. The OLED can provide three colors of red, green and blue with high saturation, and a full-color display device manufactured by using the OLED does not need an additional backlight source and has the advantages of colorful, light, thin and soft color and the like.
The core of the OLED device is a thin film structure containing various organic functional materials. Common functionalized organic materials are: hole injection materials, hole transport materials, hole blocking materials, electron injection materials, electron transport materials, electron blocking materials, and light emitting host materials and light emitting objects (dyes), and the like. When electricity is applied, electrons and holes are injected, transported to the light emitting region, and recombined therein, respectively, thereby generating excitons and emitting light.
People have developed various organic materials, and the organic materials are combined with various peculiar device structures, so that the carrier mobility can be improved, the carrier balance can be regulated and controlled, the electroluminescent efficiency can be broken through, and the attenuation of the device can be delayed. For quantum mechanical reasons, common fluorescent luminophores mainly utilize singlet excitons generated when electrons and air are combined to emit light, and are still widely applied to various OLED products. Some metal complexes, such as iridium complexes, can emit light using both triplet excitons and singlet excitons, which are called phosphorescent emitters, and the energy conversion efficiency can be increased by up to four times as compared with conventional fluorescent emitters. The thermal excitation delayed fluorescence (TADF) technology can still effectively utilize triplet excitons to achieve higher luminous efficiency without using a metal complex by promoting the conversion of triplet excitons to singlet excitons. Thermal excitation sensitized fluorescence (TASF) technology also achieves higher luminous efficiency by sensitizing the emitter by energy transfer using TADF-like materials.
As OLED products gradually enter the market, there are increasingly higher requirements on the performance of such products. The currently used OLED materials and device structures cannot completely solve the problems of OLED product efficiency, service life, cost and the like.
Therefore, there is a need in the art to develop an organic electroluminescent material that can improve the light emitting efficiency of the device, reduce the driving voltage, and prolong the lifetime.

LiF with the thickness of 0.5nm is vacuum-evaporated on the Electron Transport Layer (ETL) to be used as an electron injection layer, and an Al layer with the thickness of 150nm is used as a cathode of the device.
The organic electroluminescent devices provided in examples 2 to 21 and comparative examples 1 to 6 were fabricated in the same manner as in example 1, except that the compound P1 as an electron blocking layer material was replaced with the compounds shown in table 1.
The structures of the electron barrier materials of comparative examples 1 to 6 are as follows:
wherein R-1 and R-2 are described in detail in patent application CN109749735A, and R-3 to R-6 are described in patent application CN 110511151A.
The organic electroluminescent device prepared by the above process was subjected to the following performance measurement:
the driving voltage and current efficiency of the organic electroluminescent devices prepared in examples 1 to 21 and comparative examples 1 to 6 were measured at the same luminance using a digital source meter (Keithley2400) and a luminance meter (ST-86LA type luminance meter, photoelectric instrument factory, university of beijing) and a luminance meter. Specifically, the voltage was raised at a rate of 0.1V per second, and it was determined that the luminance of the organic electroluminescent device reached 3000cd/m2The current density is measured at the same time as the driving voltage; the ratio of the brightness to the current density is the current efficiency, and the test results are shown in table 1.
TABLE 1
As can be seen from the data in Table 1, when the compound of the invention is used as an electron barrier material of an organic electroluminescent device, the luminance of the device reaches 3000cd/m2When the material is used, the driving voltage is low below 3.8V, the current efficiency is as high as more than 18.2cd/A, the driving voltage can be effectively improved, the current efficiency can be improved, and the material is an electron barrier layer material with good performance.
When the compound R-1 of comparative example 1, which is different from the compound P602 of example 18 in that the 1-position of naphthalene is unsubstituted and the 4-position is a benzene ring in the structure of the compound R-1, is used as an electron blocking layer material for an organic electroluminescent device, the driving voltage of the device is 5.3V and the current efficiency is 11 cd/A. The turn-on voltage and current efficiency of the compound are inferior to that of P602, which may be attributed to the fact that compound P602 has better space accumulation and thus improves hole transport performance.
The arylamine group of the compound R-2 of comparative example 2 was substituted at the 1-position of the naphthalene ring, the benzene ring was substituted at the 2-position and the 3-position, and no substituent having a tert-butyl structure was contained, and when this compound was used as an electron blocking layer material for an organic electroluminescent device, the driving voltage of the device was 5.8V, the current efficiency was 10.1cd/A, and the effect was significantly inferior to that of examples 1 to 18.
The compound R-3 of comparative example 3 is compared to the compound P1 of example 1, except that the four position of the phenyl group attached to the N is not substituted with a tert-butyl group. When the compound is used as an electron barrier material of an organic electroluminescent device, the driving voltage of the device is 3.3V, and the current efficiency is 19 cd/A. The current efficiency of the compound is inferior to that of P1, which is probably attributed to that the 4-tertiary butyl in the compound P1 can provide stronger electron-supplying capability and improve the molecular space accumulation structure, thereby effectively improving the hole transport performance of the material.
The compound R-4 of comparative example 4 is different from the compound P2 of example 2 in that the terminal of biphenyl attached to N in the molecule has no tert-butyl substitution. When the compound is used as an electron barrier material of an organic electroluminescent device, the driving voltage of the device is 3.1V, and the current efficiency is 19.3 cd/A. The current efficiency of the compound is inferior to that of P2, which is probably attributed to that the 4-tertiary butyl group in the compound P2 can not only provide electron-donating capability, but also improve the structure of molecular space accumulation, thereby effectively improving the hole transport performance of the material.
The compound R-5 of comparative example 5 is different from the compound P5 of example 3 in that the biphenyl group attached to N has no tert-butyl substitution at the 4-position. When the compound is used as an electron barrier material of an organic electroluminescent device, the driving voltage of the device is 3.4V, and the current efficiency is 18.5 cd/A. The current efficiency of the compound is inferior to that of P5, which is probably attributed to that the 4-tertiary butyl in the compound P5 not only can provide stronger electron-donating capability, but also can improve the molecular space accumulation structure, thereby effectively improving the hole transport performance of the material.
The compound R-6 of comparative example 6 is different from the compound P6 of example 4 in that the terminal of 2-phenylbiphenyl group bonded to nitrogen in the molecule is not substituted with a tert-butyl group. When the compound is used as an electron barrier material of an organic electroluminescent device, the driving voltage of the device is 3.5V, and the current efficiency is 17.8 cd/A. The current efficiency of the compound is inferior to that of P6, which is probably attributed to that the tert-butyl in the compound P6 not only can provide electron-donating capability, but also can improve the structure of molecular space accumulation, thereby effectively improving the hole transport performance of the material.
Thus, in the compound provided by the invention, Ar is substituted at the 1-position of the naphthalene ring2The substitution of 2-substituted arylamine and tert-butyl structural substituent is an important factor for enabling the compound to bring excellent performance when being applied to an organic electroluminescent device.
