Abstract
The synthesis of some novel chiral liquid crystalline diacrylates and triacrylates is described. Photopolymerization of mixtures with nematic di- and triacrylates leads to polymer networks in which the helical structure of the cholesteric mesophase is frozen in. The reflection wavelength of the cholesteric phase is controlled by the composition of the mixtures and was determined by UV-VIS spectroscopy. The angular dependence of the reflection wavelength of the polymer networks and the corresponding colorimetric coordinates were evaluated.
