Abstract


In this paper, for the study of the the maleimides red material object , choose as the basic raw material Bromophenylacetonitrile synthesized a series of light-emitting materials , and discuss the relationship between the structure and luminescence properties . , The article briefly describes the the electroluminescent materials research process , focusing on the red organic electroluminescent materials are described . Red organic electroluminescent materials is divided into : an organic small molecule light emitting material , an organic metal complex material , and an organic polymer light emitting material three categories . Will focus on small organic molecules luminescent materials research progress as introduced . Second, in the course of the experiment , we had the honor to get single crystals of compounds 2-8,2-10 and 2-13 , by X - ray diffraction , we found two benzene diphenyl ethers of these compounds in the structural unit the rings are not coplanar, but has a dihedral angle of 90 ° twist . And the two benzene rings connected by the five-membered ring in the five-membered ring on both sides of the plane of the angled divaricate . Third, we the target compounds 2-9,2-10,2-11,2-12 and 2-13 spectral properties of compounds containing the structural unit of the diphenyl ether 2-10,2-11,2 spectrometry -12 and 2-13 the maximum emission wavelength at 580 nm or less , while the triphenylamine - containing structural unit of compound 2-9 compound its maximum emission wavelength at 638 nm, and reaches a true red light emission , with a certain application prospect .
