Organic compound, organic electroluminescent device, and electronic apparatus

An organic compound, having a structure obtained by fusing a formula (1) with one or two Ar groups:

• “*” indicates a site wherein the structure shown in formula (1) is fused with the Ar group;
• the Ar group is selected from the group consisting of groups shown in formulae (2-1) to (2-5):
• the Ar group is fused to any two adjacent * positions in a ring E, a ring F, a ring G, a ring H or a ring J in the formula (1);
• when the number of the Ar group is two, the two Ar groups are the same or different;
• each Ra, each Rb, each Rc, each Rd and each Re are the same or different from each other, and are each independently selected from deuterium, a halogen group, cyano, substituted or unsubstituted alkyl with 1 to 20 carbon atoms, substituted or unsubstituted cycloalkyl with 3 to 20 carbon atoms, substituted or unsubstituted aryl with 6 to 20 carbon atoms, substituted or unsubstituted heteroaryl with 3 to 20 carbon atoms, substituted or unsubstituted trialkylsilyl with 3 to 20 carbon atoms, substituted or unsubstituted haloalkyl with 1 to 20 carbon atoms, substituted or unsubstituted triarylsilyl with 18 to 24 carbon atoms, substituted or unsubstituted alkoxy with 1 to 20 carbon atoms, and substituted or unsubstituted alkylthio with 1 to 20 carbon atoms;
• na represents the number of Ra, and is selected from 0, 1, 2, 3 or 4, and when na is greater than 1, any two Ra are the same or different;
• nb represents the number of Rb, and is selected from 0, 1, 2, 3 or 4, and when nb is greater than 1, any two Rb are the same or different;
• nc represents the number of Rc, and is selected from 0, 1, 2, 3, 4 or 5, and when nc is greater than 1, any two Rc are the same or different;
• nd represents the number of Rd, and is selected from 0, 1, 2 or 3, and when nd is greater than 1, any two Rd are the same or different;
• ne represents the number of Re, and is selected from 0, 1, 2, 3, 4 or 5, and when ne is greater than 1, any two Re are the same or different;
• each R1, each R2, each R3, each R4 and each Rs are the same or different from each other, and are each independently selected from deuterium, a halogen group, cyano, trialkylsilyl with 3 to 12 carbon atoms, triarylsilyl with 18 to 24 carbon atoms, alkyl with 1 to 10 carbon atoms, cycloalkyl with 3 to 10 carbon atoms, alkoxy with 1 to 10 carbon atoms, aryl with 6 to 20 carbon atoms or heteroaryl with 3 to 20 carbon atoms;
• n1 represents the number of R1, n2 represents the number of R2, n3 represents the number of R3, n4 represents the number of R4, ns represents the number of Rs, and the ni, the na, the n3, the n4 and the n5 are each independently selected from 0, 1, 2, 3 or 4;
• and
• substituents in the Ra, the Rb, the Rc, the Rd and the Re are the same or different from each other, and are each independently selected from:
• deuterium, a halogen group, cyano, heteroaryl with 3 to 12 carbon atoms, aryl with 6 to 12 carbon atoms, trialkylsilyl with 3 to 12 carbon atoms, alkyl with 1 to 10 carbon atoms, haloalkyl with 1 to 10 carbon atoms, cycloalkyl with 3 to 10 carbon atoms, heterocycloalkyl with 2 to 10 carbon atoms, alkoxy with 1 to 10 carbon atoms, alkylthio with 1 to 10 carbon atoms, aryloxy with 6 to 12 carbon atoms, arylthio with 6 to 12 carbon atoms, alkylsulfonyl with 6 to 12 carbon atoms, trialkylphosphino with 3 to 12 carbon atoms, or trialkylboryl with 3 to 12 carbon atoms.
