For the fabrication of patterned and oriented thin film polarizer (TFP), a perylenediimide-based reactive mesogen (PDI-RM) was newly designed and synthesized. The phase behavior and anisotropic optical properties of PDI-RM were investigated by scattering, microscopic and spectroscopic analyses. Using polarized optical microscopy and X-ray diffraction, it was realized that PDI-RM formed π-π stacking among perylene core and ionic repulsion between the self-assembled nanocolumns. The patterned film was fabricated by mechanical shearing of PDI-RM H2O solution on the glass and the flexible polymer substrate and by photopolymerization. PDI-RM TFP exhibited a polarizability of 99.81% at λmax = 491 nm. Robust chemical and mechanical stabilities of PDI-RM TFP were investigated by the solvent and pencil hardness tests.
