| abstract |
The invention provides a bianthracene compound, which has the structure of formula (I): n 1 , n 2 , n 3 , and n 4 are independently 0 or 1; Ar 1 is H, C 1-60 alkyl, C 1 ～60 alkoxyl group, C 1～60 ether group, C 6～60 aryl group, C 6～60 amino group, C 6～60 arylamino group, C 5～60 fused ring group or C 5～60 heterocyclic group . Compared with the prior art, the bianthracene-containing compound provided by the present invention connects the aromatic compound through bianthracene, and by introducing Ar and Ar groups, the organic compound is applied to an organic electroluminescent device to emit blue light, and at the same time, the device emits blue light through the above-mentioned group By adjusting the light-emitting wavelength and other means, the organic electroluminescent device has high luminous efficiency and long service life. |
