When light passes through a medium with optical anisotropy, a difference in refractive index occurs, resulting in a phase difference. At this time, the birefringence and thickness of the medium can be adjusted to change the polarization of the incident light. Using these principles, we are studying anti-reflection film for OLED display high visibility. In this study, to maximize the performance of retardation film, we designed a molecular structure such that the maximum absorption wavelength is red shifted in the long axis and blue shifted in the direction perpendicular to the long axis. The long axis was synthesized as a double bond to increase the conjugation length, and because of that, the maximum absorption wavelength would be red shifted. Also, the compound was synthesized in the shape of T and H, and the difference according to the long axis was studied. The molecular structure and physical properties of the synthetic compounds were characterized by NMR, UV-Vis, DSC, and MS. |
