The present invention discloses an organic compound, an organic optoelectronic element containing the compound, and applications thereof. The organic compound is represented by the structural formula (I). Wherein, in structural formula (I), R 1 to R 3 are identically or differently selected from C1-C6 alkyl, deuterated alkyl, alkylsilyl, deuterated alkylsilyl, alkoxy, alkyl silicon Oxy group; R 4 to R 12 are identically or differently selected from one of hydrogen, deuterium, F, CN, or are alkyl, cycloalkyl, heteroalkyl, substituted or unsubstituted carbon atoms with 1 to 60 carbon atoms Substituted arylalkyl, alkoxy, substituted or unsubstituted aryloxy, alkylsilyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, alkylamino, substituted or unsubstituted arylamine groups, substituted or unsubstituted heteroarylamine groups, and combinations thereof, and at least one of R 5 , R 7 , R 9 , R 11 is not hydrogen. The organic compound of the present invention improves thermal stability and luminous efficiency, and the OLED device constructed by using the organic compound as a luminescent layer material can significantly improve the efficiency and reduce the driving voltage, and has a good application prospect. |
