Problems solved by technology

However, the above technical fluorescent probes have the following technical problems: (1) The interval between the absorption wavelength and the emission wavelength is relatively small, which may cause self-erosion
(2) The lifetime of luminescence is relatively short, and it is difficult to distinguish background fluorescence

Embodiment 1

[0032] 1. Preparation of functional N^N ligands:

[0033] Compound 1: Preparation of 1,10-phenanthroline dione derivatives

[0034] Add 5g of 1,10-phenanthroline hydrate and 25g of potassium bromide in a mixture of 100mL of concentrated sulfuric acid and 50mL of concentrated nitric acid (2:1, v:v) into a round-bottomed flask and react in a closed manner at 80°C for 3 hours, then cool Afterwards, neutralize the reaction liquid with aqueous sodium bicarbonate solution to become neutral, extract the mixed liquid, collect the organic phase, and concentrate to obtain the diketone derivative of 1,10-phenanthroline. Yield: 80%. 1 H NMR (400MHz, CDCl 3 ,298K): δ(ppm)=7.63-7.67(m,2H),8.35-8.39(dd,J=8.0Hz,2H),8.95-8.98(dd,J=8.0Hz,2H).

[0035] Compound 2: Preparation of N^N Ligands Containing Aldehyde Group (-CHO)

[0036] Under the catalysis of ammonium acetate, 180 mg of diketone derivatives of phenanthroline and 126.4 mg of terephthalaldehyde were closed in 6 mL of glacial acetic...

Abstract

The invention relates to a phosphorescent ionic iridium complex and a preparation method and application thereof, belongs to the technical field of organic photoelectric functional materials, and particularly relates to a preparation method of phosphorescent ionic iridium complexes and their application in amino acid detection, cell labeling and imaging fields. The phosphorescent ionic iridium complexes comprise a cyclometalation ligand, a metal center and an aldehyde-group-containing phenanthroline auxiliary ligand, and have the structural formula as shown in the specification, the synthesis steps of the material are simple, conditions are mild, and the method has good application prospect in the amino acid detection, cell labeling and imaging.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric materials, and in particular relates to a preparation method of a phosphorescent ion-type iridium complex and its application in the fields of amino acid detection, cell labeling and imaging. Background technique [0002] Amino acid is the basic structural unit of protein, and plays an important physiological role in human life activities. Amino acids can play the following roles through metabolism in the human body: synthesize tissue proteins; turn into acids, hormones, antibodies, creatine and other ammonia-containing substances; transform into carbohydrates and fats; oxidize into carbon dioxide, water and urea to generate energy. If the human body lacks any amino acid, it can lead to abnormal physiological functions, affect the normal progress of antibody metabolism, and cause diseases in severe cases. Therefore, the presence of amino acids in the human body not only provides imp...
