Various dichroic dyes were synthesized and applied to two different host materials for the study of optimized molecular structures of guest–host system for the coatable polarizer using liquid crystalline polymers. The host material containing planar and linear mesogens had an advantage in exhibiting high orientation orders, but easily formed disclinations due to causing the strong intermolecular attraction...
Guest–host coatable polarizers were manufactured by liquid crystalline polymers and dichroic azo dyes. The highest dichroic ratio of the polarizers was observed within the permissible limit of guest concentration, because any increase in the guest concentrations beyond the permissible limit decreased the alignment ability of the host. The orientational behavior of dye molecules in guest–host systems...
