More Information
Summary:The invention discloses an organic compound, a preparation method thereof, a display panel and a display device. The organic compound has a structure as shown in a formula I. The organic compound is a D-A-D type compound, and the molecular formula contains a novel receptor composed of quinoxaline and pyrimidine structures, a benzene ring and a donor of an aromatic amine group. Under the combined action of an acceptor and a donor, the organic compound has relatively large plane and horizontal emission dipole orientation, and is beneficial to improvement of optical coupling output efficiency; meanwhile, the energy level difference of the monotriplet state of the organic compound can be reduced, so that the organic compound has relatively high radiative transition rate and reverse intersystem crossing rate, and further, the yield of fluorescence quantum can be improved, and more excellent luminous efficiency can be obtained. In addition, when the organic compound is used as a multi-layer organic film layer mater
