Title: 6,9,15,18-TETRAHYDRO-S-INDACENO[1,2-B:5,6-B']DIFLUORENE DERIVATIVES AND USE THEREOF IN ELECTRONIC DEVICES
Abstract:
The present application relates to a compound of a formula (I) or (II) where Ar1 is the same or different at each instance and is an aryl or heteroaryl group which has 6 to 18 aromatic ring atoms and may be substituted by one or more R1 radicals; Ar2 is the same or different at each instance and is an aryl or heteroaryl group which has 6 aromatic ring atoms and may be substituted by one or more R2 radicals; and X1 may be the same or different at each instance and is BR3, C(R3)2, -C(R3) 2-C(R3)2-, -C(R3)2-O-, -C(R3)2-S-, -R3C=CR3-, -R3C=N-, Si(R3)2, Ge(R3)2, -Si(R3)2-Si(R3)2-, C=O, O, S, Se, S=O, SO2, NR3, PR3 or P(=O)R3, where two or more R3 radicals may be joined to one another and may form a ring, which is suitable for use as functional material in an electronic device, especially as emitter material in an organic electroluminescent device.
