Abstract
The present invention relates to electroactive compounds capable of undergoing a change in light absorption and refraction due to an applied electric field and a permanent change in refraction due to exposure to predetermined bands of optical radiation. The present invention also relates to electroactive compositions containing such electroactive compounds, electrooptical components comprised of such electroactive compositions and electrooptical devices comprised of such electrooptical components, as well as novel processes of making the same.
