Synthesis and Optical Properties of A Novel Blue-emitting Anthracene-based Derivative

Using Suzuki coupling reaction, a novel blue-emitting anthracene-based derivatives was designed and synthesized by introducing the electron transport branch of oxadiazole derivatives. The optical properties, thermal properties, electrochemical properties, and surface morphology of the compound were characterized. The maximum emission wavelength of this compound is 433 nm in tetrahydrofuran, and the fluorescence quantum yields is 0.94 which is 1.17 times than that of 9,10-di(2-naphthyl)anthracene. The film of this compound is continuous, compact, and smooth after annealing at 100 ℃ for 3 h, which is suitable to prepare long life and high efficiency OLED devices.
