FIELD: chemistry.SUBSTANCE: invention relates to an organic compound of formula (1), wherein each of R1-R20 is independently selected from hydrogen atoms, substituted or unsubstituted alkyl groups, substituted amino groups, substituted or unsubstituted aryl groups, wherein alkyl group is selected from a group consisting of methyl, ethyl, n-propyl, isopropyl, n-butyl, sec-butyl, tert-butyl, octyl, cyclohexyl, 1-adamantyl and 2-adamantyl groups; the amino group is selected from a group consisting of N,N-diphenylamino, N,N-dinaphthylamino, N,N-difluorenylamino, N-phenyl-N-tolylamino, N,N-ditolylamino, N-methyl-N-phenylamino, N,N-dianisolylamino, N-mesityl-N-phenylamino, N,N-dimesitylamino, N-phenyl-N-(4-tert-butylphenyl)amino, N-phenyl-N-(4-trifluoromethylphenyl)amino groups; the aryl group is selected from a group consisting of phenyl, naphthyl, indenyl, biphenyl, terphenyl and fluorenyl groups. When the alkyl group or aryl group is substituted, the substitute is selected from a group consisting of alkyl groups, alkoxy groups, amino groups, aryl groups, heterocyclic groups and aryloxy groups. The invention also relates to an organic light-emitting device, a display device, a video processing device, an illumination system, an imaging device and an irradiating light source.EFFECT: high quantum efficiency and emitting light in the green region only owing to the basic structure of the device.16 cl, 36 ex, 8 tbl, 3 dwg |
