A deep blue electroluminescence material based on π-bridged teranthracene derivative 2-tert-butyl-9,10-bis(4-(10- phenylanthracen-9-yl)phenyl)anthracene (PBTAn) was synthesized and characterized by 1H NMR, 13C NMR and HRMS. Theory calculation results show that PBTAn has a non-planar stereostructure, and the nearly degenerated highest occupied molecular orbital (HOMO, HOMO–1, HOMO–2) and lowest unoccupied molecular orbital (LUMO, LUMO+1, LUMO+2) are primarily located on the anthracene units. PBTAn shows efficient deep blue emissions both in CH2Cl2 solution (λmax=424 nm) and doped film (λmax=426 nm). The absolute photoluminescence quantum yields were measured to 0.79 and 0.83, respectively. The emission spectrum of neat PBTAn solid film (λmax=439 nm) shows a larger red-shift compared to that acquired from CH2Cl2 solution and has two shoulder peaks at about 500 and 545 nm. The material PBTAn has excellent thermal stability, the decomposition temperature and glass transition temperature were measured to be 494 and 223 ℃ under N2 atmosphere, respectively. Doped and non-doped electroluminescence devices were fabricated using PBTAn as emitter. The doped device based on PBTAn exhibits a deep blue emission at 440 nm with a CIE (Commission Internationale de l’Eclairage) coordinate of (0.15, 0.09). Meanwhile, the doped device shows high electroluminescence efficiency and low efficiency roll-off, the external quantum efficiency can reach to 4.1% and keep a higher value of 3.8% under the luminance 1000 cd•m–2.
