Description
Technical Field
The invention belongs to the field of organic photoelectricity, and particularly relates to an organic metal complex and an organic photoelectric element comprising the same, in particular to an organic electroluminescent diode.
Background
As a novel display technology, the organic light-emitting diode (OLED) has the unique advantages of self luminescence, wide viewing angle, low energy consumption, high efficiency, thinness, rich colors, high response speed, wide applicable temperature range, low driving voltage, capability of manufacturing flexible, bendable and transparent display panels, environmental friendliness and the like, can be applied to flat panel displays and new generation illumination, and can also be used as a backlight source of an LCD.
The OLED emission is divided into two modes of fluorescence emission and phosphorescence emission, and it is theorized that the ratio of a singlet excited state to a triplet excited state due to charge binding is 1: 3. Professor Baldo and Forrest in 1998 discovered that triplet phosphorescence can be utilized at room temperature, and the upper limit of the original internal quantum efficiency is increased to 100%, and triplet phosphors are often heavy metal atoms and are formed by complexes, and the strong spin-orbit coupling effect causes the energy levels of a singlet excited state and a triplet excited state to be mixed with each other by utilizing the heavy atom effect, so that the originally forbidden triplet energy is relieved to emit light in the form of phosphorescence, and the quantum efficiency is greatly improved.
At present, a host-guest light emitting system mechanism is almost completely used for a light emitting layer in an OLED assembly, namely, guest light emitting materials are doped in host materials, a common organic guest material is an iridium metal compound which is mainly applied to commercial OLED materials, but the iridium metal is very expensive and has insufficient content in earth crust, and an organic metal complex is required to replace the iridium metal complex to expand the alternative scheme of the OLED light emitting materials.
The invention finds that an organic metal compound (Pt or Pd) can improve the luminous efficiency of the organic metal compound by introducing a specific cyclic structure, a substituent group and the like, ensures that the organic metal compound has high-efficiency luminous characteristics, and can obtain high current efficiency and reduce the operating voltage of components when being applied to organic photoelectric elements, particularly organic electroluminescent devices.
