An organic electroluminescent compound represented by the following formula (III):
- wherein each of R1 to R4 is independently selected from the group consisting of hydrogen and the groups represented by formula (i), formula (ii), formula (iii), formula (iv), formula (v), formula (vi), formula (vii) and formula (viii), and at least two of the R1 to R4 are independently selected from the group consisting of the groups represented by formula (i), formula (ii), formula (iii), formula (iv), formula (v), formula (vi), formula (vii) and formula (viii):
- wherein each of R5, R6, R7, R8, R9 and R10 is independently selected from the group consisting of hydrogen, an aryl group, a heteroaryl group, a C1-C6 alkyl group, a C1-C6 alkenyl group and a C1-C6 alkynyl group;
- each of p, q, r, s, t, u and v is independently an integer between 1 and 4;
- X is selected from the group consisting of NR17, O, S, CR182, SiR192, PR20 and Se;
- each of R17, and R18, R19 and R20 is independently selected from the group consisting of hydrogen, an aryl group, a heteroaryl group, a C1-C6 alkyl group, a C1-C6 alkenyl group and a C1-C6 alkynyl group;
- each of A and D is nitrogen, and B is carbon;
- and each of R11, R12, R13, R14, R15 and R16 is independently selected from the group consisting of hydrogen, an aryl group, a heteroaryl group, a C1-C6 alkyl group, a C1-C6 alkenyl group and a C1-C6 alkynyl group.
