[0033] When N^N ligands are , the preparation of iridium complex Ir2, the specific steps are as follows:

[0034]

[0035] Synthesis of compound a: First, 2-aminobenzenethiol (4g, 32mmol) and p-hydroxybenzaldehyde (4.12mL) were added to a 250mL two-necked flask, and vacuum-filled with nitrogen-vacuumized on the double-row tube , loop three times. Second, redistilled N,N dimethylformamide (5 mL) was injected into the reaction system, and the reaction system was protected with nitrogen. Finally, the temperature of the reaction system was raised to 110° C., and the reaction was stirred for 72 hours. After the reaction was complete, the solvent was removed under reduced pressure, and recrystallized from ethanol to obtain a gray solid, namely compound a. Yield: 41.8%.

Abstract

The invention provides an iridium complex with double-emission properties, a method for preparing the iridium complex and application thereof. A structural formula of the iridium complex is shown. Theiridium complex comprises a metal iridium center, a neutral N^N auxiliary ligand and two cyclic C^N ligands. The C^N ligands contain 4-aminodiphenyl ether groups. The iridium complex, the method andthe application have the advantages that the ionic type iridium complex has the obvious double-emission properties; carbon oxygen bonds can be ruptured after the carbon oxygen bonds in the ligands actwith hypochlorite ions, accordingly, excitation states and photophysical properties of the iridium complex can be changed, and the hypochlorite ions can be detected; phosphorescence iridium complex materials have important application prospects in the aspect of biology.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric functional materials, and in particular relates to an iridium complex with dual emission properties, a preparation method thereof, and an application thereof in the detection of hypochlorite. Background technique [0002] Hypochlorite ion (ClO - ) is an important reactive oxygen species and an important intermediate product in various biological life activities. Endogenous hypochlorous acid is mainly produced in granulocytes (macrophages, monocytes, neutrophils, etc.), and is generated by the reaction of chloride ions and hydrogen peroxide under the catalysis of myeloperoxidase. Hypochlorous acid has the function of a bactericide in the body and plays an important role in the immune system. However, insufficient or excessive hypochlorous acid is harmful to the human body. Therefore, it is particularly important to be able to quickly, sensitively and accurately detect hypochlorous ...
