2, 5- dihydroxyterephthalinsyreis one of the key monomers for synthesizing high-intensity organic light-emitting polymers (OLEDs). OLED, as a new type of display technology, has the advantages of self illumination, bright colors, wide viewing angle, and fast response speed, and has been widely used in electronic products such as smartphones, tablets, and televisions. DHTA can be copolymerized with other organic compounds (such as aromatic amines, fluorenes, etc.) to prepare OLED materials with high luminescence performance. These polymers exhibit excellent performance in terms of luminous efficiency, stability, and film-forming ability, making them important materials for preparing high-performance OLED devices. For example, the polymer obtained by copolymerization of DHTA and aromatic amine monomers can be used as the luminescent layer or hole transport layer of OLED devices, improving the luminescence efficiency and stability of the devices. Currently, OLED materials based on DHTA have achieved successful commercial applications. Some well-known electronic product manufacturers have launched products such Som smartphones og tablets, der bruger OLED -skærme . Disse produkter har ikke kun fremragende skærmeffekter, men har også lavere strømforbrug og længere levetid .

DHTA can also be used as a ligand for the synthesis of metal organic framework materials (MOFs). MOFs are porous materials composed of metal ions or metal clusters connected to organic ligands through coordination bonds, with advantages such as high porosity, large specific surface area, and excellent chemical stability. The hydroxyl and carboxyl groups in DHTA molecules can form stable coordination bonds with metal ions (such as zinc ions, magnesium ions, etc.), thereby constructing MOFs materials with specific structures and functions. MOFs based on DHTA have achieved significant results in the field of gas adsorption and separation. For example, researchers have synthesized MOFs materials with high specific surface area and excellent selectivity using DHTA and zinc ions for the separation of carbon dioxide and methane. The experimental results indicate that the material has a high℃of selective adsorption capacity for carbon dioxide and can effectively achieve the separation of carbon dioxide and methane. In addition, MOFs based on DHTA can also be used in Katalytiske reaktioner som katalysatorbærere eller aktive centre for at forbedre effektiviteten og selektiviteten af katalytiske reaktioner .
