The enhancement of photoswitching in a diarylethene derivative by the incorporation of cyanobiphenyl groups.
A photochromic liquid crystal system based on a diarylethene functionalised in the 2,2'-positions and linked to 4-cyano-4'-hydroxybiphenyl groups via alkyl spacers as chromophores was synthesised and its photochromic and mesomorphic behaviour was investigated.
