Application
Photochromic materials are further developed for a light-modulating materials, optical recording media, optical switches, and functional inks.
Features And Benefits
A structural isomerization during photochromism involves photo-induced geometrical isomerizations and photo-induced ring-opening and -closure reactions. Fischer et al. first reported the photochromic behavior of spiropyrans. UV irradiation to a spiropyran undertakes a ring-opening of the spiro carbon. The structural change leads to a blue shift of photo absorption up to the visible region.
