Abstract

original image

Organic dye molecules have been included in the crystalline regions of syndiotactic polystyrene (sPS) by soaking clathrate or glass films of sPS in an azulene solution containing a plasticizer (see Figure). Highly oriented films, in which the dye molecules are oriented, are easily obtained by applying a similar procedure to an oriented glass sample.
