Abstract:
This invention relates to a composition including (a) a dopant, (b) a first host having at least one unit of Formula I, and (c) a second host compound. Formula I has the structure INSERT FORMULA I HERE In Formula I: Ar 1 , Ar 2 , and Ar 3 are the same or different and are H, D, or aryl groups. At least two of Ar 1 , Ar 2 , and Ar 3 are aryl and none of Ar 1 , Ar 2 , and Ar 3 includes an indolocarbazole moiety.
Abstract:
There is provided a compound having at least one unit of Formula I (Formula I should be inserted here) where Ar 1 , Ar 2 , and Ar 3 are the same or different and have Formula II (Formular II should be inserted here) In Formula II: R 1 is the same or different at each occurrence and is D, alkyl, or silyl, or adjacent R 1 groups can be joined together to form a 6-membered fused aromatic ring; Q is the same or different at each occurrence and is phenyl, naphthyl, substituted naphthyl, an N,O,S heterocycle, or a deuterated analog thereof; a is an integer from 1 5; b is an integer from 0-5, with the proviso that when b = 5, c = 0; and c is an integer from 0-4. In the compound not all Ar 1 , Ar 2 , and Ar 3 are the same.
