Effect of the position of cyano group in α-cyano-functionalised diarylethene chiral fluorescent photoswitches on phototunable behaviours of cholesteric liquid crystals

Two novel chiral fluorescent photoswitches bearing unsymmetric α-cyanothienylethene as emissive/photosensitive scaffold and bridged binaphthyl moieties as chiral entities are synthesised. The effec...
