Abstract:
A compound having a tricyclic nucleus and having formula (I) (I) wherein Ar is C 3 -C 25 aryl in which at least one aromatic ring atom is nitrogen; X is O, S or CR 9 R 10 ; R 1 , R 2 , R 3 , R 4 , R 5 and R 6 independently are hydrogen, deuterium, C 1 -C 12 alkyl, C 4 -C 12 aryl or C 2 -C 12 alkenyl; R 7 and R 8 independently are hydrogen, deuterium, C 1 -C 12 alkyl, C 4 -C 12 aryl or C 2 -C 12 alkenyl or R 7 and R 8 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, C 1 -C 12 alkyl, C 4 -C 12 aryl or C 2 -C 12 alkenyl; and R 11 and R 12 independently are hydrogen, deuterium, C 1 -C 12 alkyl, C 4 -C 12 aryl or C 2 -C 12 alkenyl; provided that Ar does not contain an aromatic ring attached to the tricyclic nucleus which contains more than two aromatic ring nitrogen atoms.
