Abstract

We demonstrate an easy method for the colour patterning of cholesteric liquid crystalline copolymers based on photoisomerization of a chiral comonomer. The UV dose determines the reflection colour. If two chiral compounds with opposite twist sense are copolymerized, an inversion of helical twisting sense can be observed during photoisomerization.
