The investigation of a functionalised photochromic mesogen
Most liquid crystalline photochromic systems rely on a structure, where the mesogenic group and the photochromic groups are separated by spacers. This approach uses up easily functionalisable sites for introducing LC behaviour. In this report we present a system where the mesomorphic group is integrated into the photochromic group and the termini of the alkyl groups are functionalised as olefins, which can be reacted further. The synthesis and the investigation of properties and the solid state structure are reported.
