Document Type and Number:
WIPO Patent Application WO/2021/073385
Kind Code:
A1
Abstract:
Provided is an organic compound, having a structure of the following formula (1). Rings A, B, C, D, and E each independently represent an aromatic ring or a heteroaromatic ring, and two adjacent rings can be fused to form a five-membered ring or six-membered ring containing X1 or X2; X1 and X2 are each independently selected from one of O, S, N, C, and Si; m and n are independently 0, 1, or 2, respectively, R1 to R5 are each independently selected from one of hydrogen, C1-C10 chain-like alkyls, C3-C10 cycloalkyls, C1-C10 alkoxys, halogen, cyano, nitro, hydroxyl, an ester group, silyl, amino, arylamino, heteroarylamino, substituted or unsubstituted C6-C30 aryls, and substituted or unsubstituted C3-C30 heteroaryls, and at least one of the above is formula G. When the compound is used as a light-emitting layer material in an OLED device, the compound exhibits excellent device performance and stability. An organic electroluminescent device using the compound of the general formula is further provided.
