Abstract

The present disclosure provides a composition. In an embodiment, a composition is provided and comprises a Compound 1 shown below: For Compound 1, R 1 through R 24 are the same or different. R 1 through R 24 each is independently selected from the group consisting of hydrogen, unsubstituted hydrocarbyl, substituted hydrocarbyl, cyano, alkoxy, aryloxy, and NR′ 2 . R′ is hydrogen or hydrocarbyl; wherein two or more of adjacent R 1 to R 24 may optionally form one or more ring structures. The Component Z is selected from the group consisting Group Z-1, Group Z-2, Group Z-3, Group Z-4, Group Z-5, Group Z-6 and Group Z-7 shown below: For Compound 1, one or more hydrogen atoms may optionally be substituted with deuterium.
