제목 Coatable Thin Film Polarizer by Perylenediimide-Based Reactive Mesogen
초록 For the fabrication of coatable thin film polarizer (TFP), a perylenediimide-based reactive mesogen (PDRM) was designed and synthesized. The optical properties of PDRM were investigated using spectroscopic and microscopic analyses. Based on the data of X-ray diffraction and polarized optical microscopy, it was realized that PDRM forms a lyotropic chromonic mesophase induced by the π-π stacking in the nanocolumn and ionic repulsion between nanocolumns. The oriented film was fabricated by mechanical shearing of PDRM water solution on the polymer substrate and photopolymerization. The polarizability of PDRM TFP was 99.81% at λmax = 491 nm. The coatable PDRM TFP can drive the TFP devices market to a new level. This work was supported by BK21 Plus program, the BRL 2015042417, Mid-Career Researcher Program (2016R1A2B2011041) of Korea.
