Description
Technical Field
The invention belongs to the technical field of organic photoelectric materials, and relates to a boron-containing compound and an electronic device containing the same. More particularly, the present invention relates to a boron-containing compound suitable for electronic devices, particularly organic electroluminescent devices, organic field effect transistors and organic solar cells, and an electronic device using the same.
Background
The organic electroluminescent device has a series of advantages of self-luminescence, low-voltage driving, full curing, wide viewing angle, simple composition and process and the like, and compared with a liquid crystal display, the organic electroluminescent device does not need a backlight source. Therefore, the organic electroluminescent device has wide application prospect.
Organic electroluminescent devices generally comprise an anode, a metal cathode and an organic layer sandwiched therebetween. The organic layer mainly comprises a hole injection layer, a hole transport layer, an electron blocking layer, a light emitting layer, a hole blocking layer, an electron transport layer and an electron injection layer. In addition, a host-guest structure is often used for the light-emitting layer. That is, the light emitting material is doped in the host material at a certain concentration to avoid concentration quenching and triplet-triplet annihilation, improving the light emitting efficiency. Therefore, the host material is generally required to have a higher triplet energy level and, at the same time, a higher stability.
At present, research on organic electroluminescent materials has been widely conducted in academia and industry, and a large number of organic electroluminescent materials with excellent performance have been developed. In view of the above, the future direction of organic electroluminescent devices is to develop high efficiency, long lifetime, low cost white light devices and full color display devices, but the design of thermally activated delayed fluorescent materials with high color purity still faces many key problems. Therefore, designing and searching a stable and efficient compound as a novel material of an organic electroluminescent device to overcome the defects of the organic electroluminescent device in the practical application process is a key point in the research work of the organic electroluminescent device material and the future research and development trend.

OLEDs 2-6 were prepared under the same production conditions as OLED1, except that compounds 1-1, 1-10, 1-8, 13-29, and 13-31 in Table 1 were used in place of compounds 1-3 in example 7, respectively.
Comparative examples 1 to 2: comparative preparation of OLED 1-2
Comparative OLEDs 1-2 were prepared under the same production conditions as OLED1, except that compounds DPAVBi and BD1 in Table 1 were used instead of compounds 1-3 in example 7, respectively.
The electroluminescence spectra were collected using a photon multichannel analyzer PMA-12(Hamamatsu C10027-01), which can be detected in the spectral region of 200 and 950 nm. The forward light intensity was measured using an integrating sphere (Hamamatsu a10094) to obtain the external quantum efficiency of the device. All measurements were performed at room temperature in an atmospheric environment.
