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 having Formula II. The formulae have the structures:
where Q is a fused ring linkage having the formula
In Formula I: Ar
1
is an aromatic group including at least one electron-withdrawing group or a deuterated analog; Ar
2
is an aryl group, an aromatic group including at least one electron-withdrawing group or a deuterated analog; R
1
and R
2
are the same or different at each occurrence and are H, D, aryl or deuterated aryl. In Formula II: R
3
is the same or different at each occurrence and is D, aryl, or deuterated aryl, with the proviso that at least one R
3
is aryl or deuterated aryl; R
4
and R
5
are the same or different at each occurrence and are D, aryl, or deuterated aryl; a is an integer from 1-4; and b and c are the same or different and are an integer from 0-4.
