Problems solved by technology

However, the synthesis of organometallic iridium complexes at present is due to the poor solubility of the traditional mixed reaction solvent of ethylene glycol ether and water to the reaction intermediate metal iridium dimer complexes, resulting in very low reaction yields or even no reaction.
In addition, the mixed solvent of ethylene glycol ether and water is a high-boiling solvent, and it needs to be dried in a vacuum oven for nearly 10 hours to completely remove it after the reaction, which consumes energy and takes a long time

Abstract

The invention discloses an organic metal iridium complex luminescent material and a synthetic method of the material. The synthetic method disclosed by the invention comprises the following steps of: mixing an organic complex with iridium chloride hydrate in nitrogen atmosphere, subsequently adding a mixed solvent of tetrahydrofuran and water, heating in the nitrogen atmosphere and cooling to the room temperature; separating the reaction mixture liquid to acquire a tetrahydrofuran organic layer, and drying to remove the tetrahydrofuran solvent so as to acquire a metal iridium dimer complex; completely dissolving the metal iridium dimer complex and acetyl acetone thallium in dichloromethane and stirring at the room temperature in the nitrogen atmosphere; then purifying the metal iridium dimer complex on a chromatography silica gel column or a self-manufactured thin layer silica gel chromatography plate to acquire the final product which is the organic metal iridium complex luminescent material. According to the invention, the mixed solvent of the tetrahydrofuran and the water is taken as a reaction solvent for synthesizing the organic metal iridium complex, so that the synthetic yield of the organic metal iridium complex can be significantly improved; and the reaction after-treatment is simplified, so that the after-treatment time is shortened and the energy resources are saved.

Description

technical field [0001] The invention relates to the field of organic luminescent materials, in particular to an organic metal iridium complex luminescent material and a synthesis method thereof. Background technique [0002] Organic luminescent material is an organic compound that can emit light under the condition of light excitation or electric excitation. All kinds of new displays and lighting lamps made of this material have low operating voltage, high luminous brightness, energy saving and environmental protection. In particular, organometallic iridium complex luminescent materials are attracting more and more attention because they can use molecular singlet and triplet states to emit light at the same time, so that the internal quantum efficiency of luminescence can theoretically reach 100%. However, in the synthesis of organometallic iridium complexes, the reaction yield is very low or even non-reactive due to the poor solubility of the reaction intermediate product ...
