What is Arylpropenoates as Photoactive Units in Photocontrollable Polymers about?
## Abstract The synthesis of photochemical properties of a range of arylpropenoates are described and their suitability as photoactive units for the reversible manipulation of polymer properties assessed. The __Z__ and __E__ isomers of the 1‐naphthyl‐, 1‐(4‐methoxynaphthyl)‐ and 9‐phenanthryl‐ derivatives have sufficiently different absorption characteristics to allow their selective exciation to give photostationary states having high concentrations of each isomer. Incorporation of the photoactive units into methacrylate based polymers changes the photostationary state concentrations of the __Z__ and __E__ isomers but the effect on the 1‐(4‐methoxynaphthyl)‐derivative is small and here the photointerconversion is not accompanied by fatigue. The 9‐anthryl derivative undergoes facile (4π + 4π) photodimerization and this may have potential as a reversible crosslinking mechanism.
