摘要：
Photochromic materials comprising indeno- fused naphthopyrans having substituents comprising a 4-fluorcVhenyl group and a 4-aminophenyl group bonded to the 3- position of the indeno- fused naphthopyran are disclosed. The photochromic materials may exhibit faster fade rates as compared to similar indeno-fiised naphthopyrans without a 4- fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fiised naphthopyran. Substituted 2-propyn-l-ols utilized for the synthesis of the indeno-fused naphthopyrans disclosed herein are disclosed. Photochromic compositions and articles, such as optical elements, incorporating the photochromic materials disclosed herein are also disclosed.
