摘要

There is provided a hole transport compound having Formula I or Formula II:;
Ar1 is the same or different at each occurrence and can be phenylene, naphthylene, or binaphthylene. Ar2 is the same or different at each occurrence and can be phenyl, biphenyl, terphenyl, naphthyl, or binaphthyl. m and n are the same or different and are an integer greater than 0. T is the same or different at each occurrence and is a conjugated moiety including at least one triarylamino group. The T moiety is connected in a non-planar configuration.

1. A liquid processable hole transport compound having Formula I or Formula II: wherein: Ar1 is the same or different at each occurrence and is selected from the group consisting of phenylene, naphthylene, and binaphthylene; Ar2 is the same or different at each occurrence and is selected from the group consisting of phenyl, biphenyl, terphenyl, naphthyl, and binaphthyl; m and n are the same or different and each is an integer greater than 0; and T is the same or different at each occurrence and is a conjugated moiety including at least one triarylamino group, wherein the moiety is connected in a non-planar configuration;wherein the compound comprises at least one set of adjacent aryl groups selected from one of the following: where R represents an alkyl, aryl, alkoxy, or aryloxy group and the dashed line represents a possible point of attachment, further comprising at least two sets of adjacent naphthyl groups.
