A series of novel host blue-emitting materials based on anthracene have been synthesized and investigated in which, a π-electron-rich dibenzothiophene moiety was introduced as a side group to fine adjust the HOMO/LUMO levels of the anthracene and enhance the ability of hole-transport and electron-injection. These materials exhibit good film-forming capabilities, and display strong blue fluorescence in solution. To explore the electroluminescent properties of these materials, sky blue devices of 2-TNATA (60 nm)/NPB (10 nm)/Host: BUBD-1 (40 nm)/Alq3 (15 nm)/LiF (1 nm)/Al (150 nm) were fabricated. For the device with 9, 10-bis(dibenzothiophen-4-yl)anthracene as the host, an electroluminescence efficiency of 13.14 cd/A and 6.76 lm/W at 20 mA/cm2 and 6.09 V were achieved, with Commission Internationale d'Eclairage (CIEx,y) color coordinates of (x = 0.15, y = 0.30).

The invention provides a compound as shown in a general formula (I), which has a mother structure of sym-triphenyl substituted anthracene, is high in bond energy among atoms, has good thermal stability, is beneficial to solid-state accumulation among molecules, is large in bandwidth, has a light-emitting region in a blue light region, is high in light-emitting intensity, and has a proper energy level with adjacent levels. And injection and migration of excitons are facilitated. When the compound is used as a blue light host material in a luminescent layer, the driving voltage of an organic electroluminescent device can be effectively reduced, the luminous efficiency is improved, and the service life is prolonged. The invention also provides an organic electroluminescent device and a display device containing the compound of the general formula (I).
