The immobilization of the trans-4-[4-(dimethylamino)]stilbazolium p-toluenesulfonate (DAST) nanocrystals in a dispersion, which were oriented in magnetic fields, was studied. The odorless, transparent, and rubber-like solid was obtained by photocuring of the dispersion in lauryl acrylate. The relaxation of the oriented nanocrystals was not observed at 100 °C for 24 hours. Maximum contrast of the absorbance through a parallel and perpendicular polarized light was approximately 0.43 at 555 nm.
