Abstract

The invention belongs to the field of organic photoelectricity, and particularly relates to an iridium metal complex and an organic photoelectric element containing the same, in particular to an organic light-emitting diode. The structure of the iridium metal complex is shown in the formula (I) in the specification, and the formula (I) of the iridium metal complex and the organic photoelectric element can be understood by referring to the specific description provided in the invention. The iridium metal complex disclosed by the invention is applied to a light-emitting layer of an organic light-emitting diode, so that the current efficiency of a light-emitting element is improved, the driving voltage is reduced, the service life is obviously prolonged. The iridium metal complex has a good commercial prospect.

Description

Technical field[0001]The present invention belongs to the field of organic photoelectric, and more particularly to a ruthenium metal complex and a photovoltaic element comprising therethrough, particularly an organic electroluminescent diode.Background technique[0002]As a new type of display technology, the organic electroluminescent diode (OLED) has self-illuminating, wide viewing angle, low energy consumption, high efficiency, thin color, fast response, has a wide range of temperature range, low drive voltage, can make flexibility The unique advantages of bending and transparent display panels and environmentally friendly, which can be applied to the tablet display and a new generation of illumination, or as a backlight of the LCD.[0003]Since the inventive inventions in the 1980s, organic electroluminescent devices have been applied in the industry. OLED is divided into two ways of fluorescence and phosphorescence. According to theoretical speculation, the single excitation state ...
