Abstract
The synthesis of some novel chiral liquid crystalline diacrylates and triacrylates is described. Photopolymerization of mixtures with nemati c di-and triacrylates leads to polymer networks in which the helical s tructure of the cholesteric mesophase is frozen in. The reflection wav elength of the cholesteric phase is controlled by the composition of t he mixtures and was determined by W-VIS spectroscopy. The angular depe ndence of the reflection wavelength of the polymer networks and the co rresponding colorimetric coordinates were evaluated.
