Abstract

The invention belongs to the field of organic photoelectricity, and particularly relates to an iridium metal complex and an organic photoelectric element using the iridium metal complex, in particular to an organic light-emitting diode. The structure of the iridium metal complex is shown as a formula (I) in the specification, wherein (L^Z) is selected from astructural formula represented by A, and the formula (I) of the iridium metal complex and the organic optoelectronic element may be understood by referring to the specific description provided herein. The iridium metal complex disclosed by the invention is applied to a light-emitting layer of the 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, and the iridium metal complex has a very good commercialization prospect.

Description

technical field [0001] The invention belongs to the field of organic photoelectricity, and in particular relates to an iridium metal complex and a photoelectric element containing it, in particular to an organic electroluminescent diode. Background technique [0002] As a new type of display technology, organic light-emitting diode (OLED) has self-illumination, wide viewing angle, low energy consumption, high efficiency, thin, rich colors, fast response, wide applicable temperature range, low driving voltage, and flexible The unique advantages of flexible and transparent display panels and environmental friendliness can be applied to flat panel displays and new generation lighting, and can also be used as LCD backlight. [0003] OLED luminescence is divided into two ways: fluorescence luminescence and phosphorescence luminescence. According to theoretical speculation, the ratio of the singlet excited state to the triplet excited state caused by the combination of charges is ...
