Nitrogen-containing compound, organic electroluminescent device and electronic apparatus

A nitrogen-containing compound, wherein the structural formula of the nitrogen-containing compound is as shown in formula 1:

• wherein ring A is benzene ring;
• X is selected from C (Z1Z2), N(Z3), O or S;
• Z1 and Z2 are the same or different, and are each independently selected from:
• methyl, or substituted or unsubstituted aryl with 6 to 30 carbon atoms, or substituted or unsubstituted heteroaryl with 3 to 30 carbon atoms, or alternatively, Z1 and Z2 are connected with each other to form saturated or unsaturated 5- to -13-membered rings together with the atoms to which they are jointly connected;
• Z3 is selected from substituted or unsubstituted aryl with 6 to 30 carbon atoms, or substituted or unsubstituted heteroaryl with 3 to 30 carbon atoms;
• the substituents of the Z1, Z2 and Z3 are the same or different from each other, and are each independently selected from:
• deuterium, fluorine, chlorine, bromine, cyano, methyl, aryl with 6 to 20 carbon atoms, or heteroaryl with 6 to 18 carbon atoms;
• Y, R1, R2 and R3 are the same or different, and are each independently selected from:
• deuterium, fluorine, chlorine, bromine, or cyano;
• n and n3 are the same or different, and are each independently selected from 0, 1, 2, 3 or 4;
• n1 and n2 are the same or different, and are each independently selected from 0, 1, 2 or 3;
• when n is 2, 3 or 4, any two Y are the same or different;
• when n1 is 2 or 3, any two R1 are the same or different;
• when n2 is 2 or 3, any two R2 are the same or different;
• when n3 is 2, 3 or 4, any two R3 are the same or different;
• L is selected from:
• single bond or unsubstituted T1 or substituted T1, wherein unsubstituted T1 is selected from the group consisting of the following substituents:
• substituted T1 is a group formed by substituting the unsubstituted T1 by one or more substituent(s) selected from deuterium, fluorine, chlorine, cyano and methyl and when a plurality of substituents are included on the substituted T1 any two substituents are the same or different.
