Organic compound, electronic element and electronic apparatus

An organic compound having the structure shown in Formula 1:

• wherein R1 and R2 are the same or different, and are each independently selected from a substituted or unsubstituted aryl with 6 to 25 carbon atoms, a substituted or unsubstituted heteroaryl with 5 to 25 carbon atoms, an alkyl with 1 to 10 carbon atoms, or a cycloalkyl with 3 to 10 carbon atoms;
• Ar is selected from a substituted or unsubstituted aryl with 6 to 21 carbon atoms, or a substituted or unsubstituted heteroaryl with 5 to 20 carbon atoms;
• L1, L2 and L3 are the same or different, and are each independently selected from a single bond, a substituted or unsubstituted arylene with 6 to 15 carbon atoms, or a heteroarylene with 5 to 15 carbon atoms;
• the substituents of R1, R2, Ar, L1, L2 and L3 are the same or different, and are each independently selected from deuterium, a cyano, an alkyl with 1 to 10 carbon atoms, a deuterated alkyl with 1 to 10 carbon atoms, an alkoxy with 1 to 10 carbon atoms, an alkylthio with 1 to 10 carbon atoms, an aryl with 6 to 12 carbon atoms, a heteroaryl with 5 to 12 carbon atoms, or a cycloalkyl with 3 to 10 carbon atoms;
