Abstract

Light emitting polymers can include a plurality of arylene monomeric units and a plurality of soft segment units independently selected from soft segment end caps; soft segment side chains coupled to a portion, but not all, of the arylene monomeric units; internal soft segment monomeric units; and combinations thereof. These light emitting polymers can be used in forming electroluminescent devices or other articles.
