, (2020/08/19)
The present invention relates to a hydrogen bonding mixture for a reverse wavelength dispersion compensation film exhibiting reverse wavelength dispersion characteristics according to a self-assembly arrangement between a host-guest reactive mesogen capable of hydrogen bonding as one layer structure and a compensation film including the same. Films produced by the present invention induce self-assembly between more stable host-guest reactive mesogens due to intermolecular host-guest interactions through hydrogen bonding. A wavelength dispersion compensation film is provided to have improved orientation and to have a wavelength dispersion characteristic close to an ideal value by comparison with an existing one-layer reverse wavelength dispersion compensation film. , The reverse wavelength dispersion compensation film proposed in the present invention can be used for preventing an OLED or viewing angle of LCD. The reverse wavelength dispersion compensation film of the present invention can reduce the thickness of the device as compared with an existing laminated reverse wavelength dispersion compensation film.

Two series of click chemistry assisted alkoxymethyl-1H-[1,2,3]-triazol-1-yl containing sidechain liquid-crystalline polymethacrylates were synthesized by free radical polymerization technique. Mesogen was linked to backbone through various spacer units. Monomers and polymers were characterized by FT-IR, 1H and 13C-NMR spectral techniques. Thermal stability of polymers was confirmed by thermogravimetric analysis. Mesomorphic property and phase transition temperature of polymers were analysed by differential scanning calorimetry and polarized optical microscopy. Phase transition temperature and mesomorphic property of polymers with respect to insertion of polar alkoxy group on terminal triazole ring and spacer length between backbone and mesogen were investigated. Polymers exhibited grainy like textures under polarized optical microscopy. Spacer length between mesogen and backbone alters phase transition temperature of the polymers. Indian Academy of Sciences.
