Arylpropenoates as photoactive units in photocontrollable polymers

Proctor, A.D., Gilbert, A. and Mitchell, G.R. (1992) Arylpropenoates as photoactive units in photocontrollable polymers. Macromolecular Chemistry and Physics, 193 (6). pp. 1499-1508. ISSN 1022-1352 doi: 10.1002/macp.1992.021930626

Abstract/Summary

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.
