lengths was developed. Copolymers with methyl methacrylate and cholesteric monomers were prepared; the latter showed liquid crystalline properties. The rate constant of the photocyclization to the bis(β-lactame) structure of various spin-coated polymeric films was determined by irradiation with a HeCd laser (442 nm), whereby two different parameters controlling the rate constant could be found. It was shown

The invention relates to compounds of Formula (I):
The invention further relates to liquid crystal compositions comprising compounds of Formula (I); compositions further comprising one or more chiral compounds; and polymer networks derived from the polymerization of the liquid crystal compositions. Another embodiment relates to processes for providing compounds of Formula (I).
