An antireflective film by a coating process has more advantages than that by a stretching process in respect of thickness and uniformity. To develop a single-layered compensation film, we programmed a guest reactive mesogen (GRM) which contains the conjugated backbone with two imine bonds and two alkyl chains. The single-layered compensators were fabricated by coating, self-assembly and photopolymerization of the smectic host RM and XGRM mixtures with different mixing ratios. Through the optical measurements, it was found that the optimized content of GRM was 40 wt%. The optimized single-layered compensator shows the ideal molecular arrangement and negative dispersion retardation, resulted from host-guest molecular self-assembly. This work indicates importance of understanding phase and self-assembly behaviors of the host-guest system in fabricating single-layered compensator.
