Octupolar films containing 1,3,5‐tricyano‐2,4,6‐tris( p ‐diethylaminostyryl)benzene in a polymethylmetacrylate matrix are prepared by using free‐casting and spin‐coating methods and their physical properties are characterized by using polarization microscopy, X‐ray diffraction spectra, and second‐harmonic generation (see figure). The films exhibit an optimum molecular packing that can find useful applications in electro‐optic devices.
