Abstract
We have found that the presence of a methacrylate group on an azobenzene el ectro-optic chromophore can provide an enhancement in photostability of up to one or two orders of magnitude. Systematic studies involving the change in chromophore structure and atmospheric environment indicate that the phot ostabilization is due to antioxidant action by the unsaturated functional g roup.
