| Abstract: | Cholesteric liquid crystalline monomers undergo efficient photopolymerization to “freeze in” the planar texture characteristic of low molar mass cholesteric liquid crystals. The monomers consist of polymerizable moieties separated from the cholesteryl mesogens by flexible spacer groups. Individual monomers and mixtures give homopolymers and copolymers, respectively, that exhibit cholesteric textures to within 10 to 15ddot]C of the isotropic transition. |
