Description
Technical Field
The invention belongs to the technical field of organic photoelectric materials, and relates to acenaphthene and aza-naphthalene derivatives and an electronic device containing the same. More particularly, the present invention relates to acenaphthoazaphthalenes derivatives suitable for use in electronic devices, particularly organic electroluminescent devices, organic field effect transistors and organic solar cells, and electronic devices 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 many key issues still face for organic electroluminescent materials with deep red and near infrared colors. 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.

The invention aims to provide an acenaphthene aza-naphthalene derivative. The acenaphthene aza-naphthalene derivative has high thermal stability, good transmission performance, high fluorescence quantum yield and simple preparation method, and the organic light-emitting device prepared from the acenaphthene aza-naphthalene derivative has the advantages of high light-emitting efficiency, long service life, long light-emitting wavelength and low driving voltage, and is an organic electroluminescent material with excellent performance.
It is another object of the present invention to provide an electronic device using the acenaphthoazaphthalene derivative, which has advantages of high efficiency, high durability and long lifetime.
The acenaphthene aza-naphthalene derivative compound adopted by the invention has a special condensed ring structure and has higher thermal stability, chemical stability and carrier transport property. The light color of the acenaphtho-pyrazine derivatives reported at present does not reach an infrared region, so that the derivatives have appropriate singlet states, triplet states, molecular orbital energy levels, strong electron-withdrawing capability and excellent fluorescence quantum yield by introducing more electron-withdrawing elements. Therefore, the organic electroluminescent material is introduced into molecules with electroluminescent characteristics, so that the stability and the luminous efficiency of a device are improved, and the driving voltage of the device is reduced. In addition, the acenaphthene aza-naphthalene derivative compound has stronger electron pulling capability, can emit light more infrared, has more advantages in the fields of health physiotherapy and near infrared detection, has better conductivity and the like.
