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.
