Color tunability in photochromic naphthopyrans
Photochromic naphthopyrans are of particular interest due to their wide use in applications such as switchable eyewear, security devices and novelty items. The spectral properties of the activated form are important in many of these applications. This paper reports the effect of substituents on the visible absorption of the activated form(s). In addition to color, other photochromic properties of naphthopyrans are briefly discussed.
