In this paper, the synthesis, photo-reaction and photo-induced liquid crystal alignment of a imide oligomer with a terminated cinnamate group are reported. The imide oligomer was synthesized by the chemical imidization of the polyamic acid derived from 3,3',4,4'-benzophenone tetracarboxylic dianhydride, 4,4'-oxydianiline, and 4-aminophenol followed by the attachment of the cinnamate group to the imide...
