Ambient-temperature liquid-crystalline bismethacrylates based on cholesterol: Cholesteric and smectic thermosets
Liquid-crystalline (LC) thermosets make it possible ro fix LC order permanently and to produce materials with anisotropic properties of interest in electronics and optics. Branched LC bismethacrylates based on cholesterol as the mesogenic unit are described (see Figure) that exhibit stable mesophases at ambient temperature. A convenient pathway to photo-crosslinkable LC monomers from a commercial bismethacrylate is introduced.
