A novel carbazole derivative containing dimesitylboron groups, 3-dimesitylboryl-9-(4-(3-dimesitylborylcarbazoly)phenyl)carbazole has been successfully synthesized by introducing two dimesitylboron groups (two electron-acceptors) to 3-position and 3 '-position of 1, 4-bis(carbazolyl)benzene (an electron-donor), respectively. The structure of the compound was fully characterized by elemental analysis, mass spectrometry and proton nuclear magnetic resonance spectroscopy methods. The electrochemical and photophysical properties of the compound were studied by electrochemical methods, UV-vis absorption spectroscopy and fluorescence spectroscopy. Our results show that the compound exhibits excellent thermal stability (T-d = 190 degrees C) and electrochemical stability as well as aggregation induced emission properties. The multi-layered organic light-emitting diodes device was fabricated by using the compound as non-doped emitter. The device shows good electroluminescent performances with the same blue emission color (lambda = 478 nm) at different voltages, a turn-on voltage of 3.8 V, a maximum luminance of 2784 cd/m(2) and a maximum luminance efficiency of 3.25 cd/A.
