Description

Organic compound and application thereof
Technical Field
The present invention relates to an organic compound, and more particularly, to a compound useful for an organic electroluminescent device, and also to an organic electroluminescent device using the same.
Background
Organic Light Emission Diodes (OLED) are a kind of devices with sandwich-like structure, which includes positive and negative electrode films and Organic functional material layers sandwiched between the electrode films. And applying voltage to the electrodes of the OLED device, injecting positive charges from the positive electrode and injecting negative charges from the negative electrode, and transferring the positive charges and the negative charges in the organic layer under the action of an electric field to meet for composite luminescence. Because the OLED device has the advantages of high brightness, fast response, wide viewing angle, simple process, flexibility and the like, the OLED device is concerned in the field of novel display technology and novel illumination technology. At present, the technology is widely applied to display panels of products such as novel lighting lamps, smart phones and tablet computers, and further expands the application field of large-size display products such as televisions, and is a novel display technology with fast development and high technical requirements.
In the aspect of selection of OLED luminescent materials, the singlet luminescent fluorescent material has the advantages of long service life, low price and low efficiency; triplet-emitting phosphorescent materials are efficient, but expensive, and the problem of lifetime of blue materials has not been solved. Adachi at kyushu university of japan proposes a new class of organic light emitting materials, i.e., thermally Activated Delayed Fluorescence (TADF) materials. The material utilizes the separation of a donor receptor to obtain a smaller singlet-triplet energy gap (delta E) ST )(<0.3 eV) so that triplet excitons may be converted into singlet excitons through reverse intersystem crossing (RISC) to emit light, and thus the internal quantum efficiency of the device may reach 100%.
In the prior art, a new structural compound design is performed by adopting a multiple resonance induced thermal activation delayed fluorescence (MR-TADF) strategy, for example, patent applications CN107851724, CN108431984, CN110407858 and the like design polycyclic aromatic compounds formed by connecting a plurality of aromatic rings by boron atoms and nitrogen atoms or oxygen atoms, i.e., a special rigid molecular system containing boron (B) atoms and nitrogen (N) atoms is constructed. Compared with a donor-receptor type TADF compound, the MR-TADF molecule has high radiative transition rate and narrower half-peak width, but most of the existing BN-type MR molecule light color is in a sky blue-green light region, the half-peak width is mostly about 30nm, and the requirements of a new generation ultra-high definition video standard BT.2020 cannot be met.
