Zusammenfassung:Compounds having a structure according to Formula I, G1-L1-G2, or Formula V, are described. In Formula I, G1 and G2 independently have a structure of Formula II, In the structures of Formula I, II, and V, L1 connects one of rings A1-A4 of G1 to one of rings A1-A4 of G2; L1 is selected from a direct bond, BR, NR, PR, O, S, Se, C═O, S═O, SO2, SiRR′, GeRR′, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; each ring A1, A2, A3, and A4, as well as R, R′R″, and R1 to R19 can be hydrogen or a variety of substituents, including a fused ring between adjacent substituents; and at least two adjacent R1 to R16 on the same ring are Formulations and devices, such as an OLEDs, that include the compound of Formula I or V are also described.
