Photochromism of spiropyrans and spirooxazines in the solid state: low temperature enhances photocoloration

In this study we have revealed that spiropyrans and spirooxazines, which have long been believed to be non-photochromic in the solid state, are generally photochromic in the solid state at least at low temperatures and that their photoreactivity increases greatly as the temperature is lowered.
