摘要
In this work, a new luminescent material of a small-molecule stilbene derivative (BABCz) containing anthracene was designed and synthesized by three simple reactions. The material was characterized by H-1-NMR, FTMS, and X-ray and tested using TGA, DSC, UV/Vis, fluorescence spectroscopy, and atomic force microscopy. The results demonstrate that BABCz has luminescence properties with good thermal stability and can be doped with 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP) to prepare highly uniform films, which allows the fabrication of OLED devices with ITO/Cs2CO3:BABCz/CBP:BABCz/MoO3/Al configuration. This simplest device in the sandwich structure emits green light at 6.6-12 V and has a brightness of 2300 cd/m(2), indicating the potential of this material in OLED manufacturing.
