Since the research by Kodak in 1987, organic lightȋemitting diodes (OLEDs) have been attractedmany interest and seen as one of the most potential technologies for future displays. A number of materials have been developed and improved in order to fulfil the requirements of this application. However, Whe efficiency and longevity of blue OLED materials have still been great problems for industrialization. The development of new high-efficiency small-molecule blue light materials will be related to the future of OLED materials.Small molecules based on anthracene have demonstrated outstanding blue OLED material properties in many laboratory research, especially in the luminous efficiency and color purity of materials. Pyrene- based also exhibits high efficiency and high electron mobility in many materials. Therefore, on the basis of predecessors, we have improved and designed several new small molecule blue OLED materials.In this paper, we developed one new twisted rigid blue light-emitting pyrene-based and two organic blue light-emitting anthracene-based materials were designed and synthesized. These materials were synthesized with boration reaction and Suzuki coupling reaction. After that the material structures were confirmed with 1H NMR, 13C NMR, and mass spectroscopy. The Optical properties and Electrochemical properties were characterized with UV-vis absorption, photoluminescence and cyclic voltammetry as well. The thermal properties also were characterized by TGA and DSC. The Homo of these three new structure materials are -5.41eV, -5.37eV and -5.53eV respectively. At the same time their respective LUMO are -2.30, -2.37 and -2.52. Through experimental characterization and calculation, these materials have the right band gap.We predict that these materials will show good optical properties
