| 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 alkoxy 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 aromatic compounds through bianthracene, and by introducing Ar and Ar 1 groups, the device emits blue light after the organic compound is applied to an organic electroluminescence device, and at the same time, the above-mentioned groups are used to emit blue light. The organic electroluminescent device has high luminous efficiency and long service life by means of adjusting the luminescent wavelength and other means. |
