In this study, the H-shape reactive mesogen molecular structure including the C=N bond was designed so that the birefringence increases as the wavelength increases. The molecular structure used in the direction perpendicular to the long axis was synthesized by introducing a photocrosslinkable functional group. For the molecular structure of the long axis, imine bonds were synthesized through a Schiff base using various kinds of diamines including aromatic compounds. The molecular structure of the H-shape containing the imine bond was confirmed by NMR, UV-Vis, DSC, and FAB-MS. When H-shape reactive mesogen compound containing an imine bond was mixed with a positive dispersed host liquid crystal, negative dispersion properties were observed. |
