| abstract |
The invention discloses a novel organic compound, which has the structure of the following formula: R 1 , R 1' , R 2 , R 2' , R 3 and R 3' are each independently selected from C1-C10 alkyl, C3-C10 cycloalkyl, C6-C30 aryl, C3-C30 alkyl One of heteroaryl groups; a, a', b, b', c and c' are independently selected from 0 or 1, and a+a'+b+b'+c+c'≥3; d , e and f are independently selected from 0, 1, 2 or 3, and are not 0 at the same time; R 4 -R 6 are independently selected from C1-C10 alkyl, C3-C10 cycloalkyl, C6-C30 One of aryl, C3-C30 heteroaryl, C6-C30 arylamino, C3-C30 heteroarylamino, and at least one of R 4 to R 6 is selected from C6-C30 aryl, C3-C30 Heteroaryl, C6-C30 arylamino, C3-C30 heteroarylamino. When the compound of the present invention is used as a material in the light-emitting layer of an OLED device, it exhibits excellent device performance and stability. The present invention simultaneously protects the organic electroluminescent device using the compound of the above general formula. |
