| 摘 要： | Two kinds of novel blue-emitting materials, anthracene-based derivatives, are synthesized by the Suzuki coupling reaction. It is worth noting that the maximum emission wavelengths of the two materials are 441 and444 nm in tetrahydrofuran and 456 and 454 nm in film states, which are the typical blue fluorescence and the fluorescence quantum yields of them are 0.87 and 1.12 by using 9,10-diphenylanthracene eΦf=0.90 T as a calibration standard. The full width at half maximum of them are 56, 55 nm in solution, respectively, presenting good color purity. Both of them display superior thermal properties and electrochemical properties.Scanning electronic microscope results show that the films of two compounds are continuous, compact, and smooth after 100°C for 3 h. These data indicate their potential to be prepared for high efficiency and long operation lifetime organic light-emitting diodes devices.
