Our final aim is the establishment of the preparation method of syndiotactic polystyrene (sPS) films where photo-functional molecules are three-dimensionally arrayed with a regular orientation. We prepared sPS films including 7-amino-4-methylcoumarin (AMC), a typical dye molecule, by some different procedures and examined the crystalline structure and the orientation of AMC by WAXD together with measurements of polarized fluorescence by rotation of a sample (PFR). The exposure of sublimated AMC gas to stretched sPS films only produced trans mesomorphic phase of sPS without forming sPS/AMC cocrystals. Finally, the preparation method by soaking stretched sPS films in CS2 solution of AMC was found to be a good way to produce sPS films having regularly oriented sPS/AMC cocrystals, though the fraction of cocrystals was still not high.
