摘要：
A compound having a tricyclic nucleus and having formula (I);;wherein Ar is C3-C25 aryl in which at least one aromatic ring atom is nitrogen; X is O, S or CR9R10; R1, R2, R3, R4, R5 and R6 independently are hydrogen, deuterium, C1-C12 alkyl, C4-C12 aryl or C2-C12 alkenyl; R7 and R8 independently are hydrogen, deuterium, C1-C12 alkyl, C4-C12 aryl or C2-C12 alkenyl or R7 and R8 groups attached to a nitrogen atom are joined by a single bond, O, S or CR11R12 to form a single nitrogen-containing substituent; R9 and R10 independently are hydrogen, deuterium, C1-C12 alkyl, C4-C12 aryl or C2-C12 alkenyl; and R11 and R12 independently are hydrogen, deuterium, C1-C12 alkyl, C4-C12 aryl or C2-C12 alkenyl; provided that Ar does not contain an aromatic ring attached to the tricyclic nucleus which contains more than two aromatic ring nitrogen atoms.
