  PHOTOCHROMIC MATERIALS THAT INCLUDE 6-AMINO SUBSTITUTED INDENO-FUSED NAPHTHOPYRANS

  摘要：

  本发明涉及包括某些吲哚并螺[3,3,3]己喹喙的光致变色材料。这些吲哚并螺[3,3,3]己喹喙在6位与氨基团（例如哌啶基或吗啉基）键合，并且在11位可能与卤素基团（例如氟基）键合。本发明的光致变色材料可能具有闭合形式的电磁辐射吸收光谱，其相对于类似的光致变色材料向更长波长（例如大于390纳米的波长）移动。本发明还涉及包括本发明的光致变色材料的光学元件，例如眼镜。

  Photochromic materials comprising indeno-fused naphthopyrans having substituents comprising a 4-fluorophenyl 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-fused naphthopyrans without a 4-fluorophenyl group and a 4-aminophenyl group bonded to the 3-position of the indeno-fused naphthopyran. Substituted 2-propyn-1-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.

  本文披露了一种包含取代基的吲哚并萘噻吩的光致变色材料，该取代基包括与吲哚并萘噻吩的3位键合的4-氟苯基和4-氨基苯基。与没有4-氟苯基和4-氨基苯基键合到吲哚并萘噻吩的类似吲哚并萘噻吩相比，光致变色材料可能表现出更快的褪色速率。本文还披露了用于合成本文所披露的吲哚并萘噻吩的取代2-丙炔-1-醇。本文还披露了包含本文所披露的光致变色材料的光致变色组合物和物品，例如光学元件。

  Photochromic materials comprising indeno-fused naphthopyrans having a first electron-withdrawing substituent and, in certain non-limiting embodiments, a second electron-withdrawing substituent are disclosed. The photochromic materials according to the various embodiments may display faster fade rates, bathochromic shift, and higher performance ratings compared to comparable indeno-fused naphthopyrans without the electron-withdrawing substituents. Photochromic compositions and articles, such as optical elements, incorporating the photochromic materials are also disclosed.

  本发明揭示了包括具有第一电子受体取代基和在某些非限制性实施例中具有第二电子受体取代基的茚并萘噻吩的光致变色材料。根据各种实施例，光致变色材料可能显示比没有电子受体取代基的茚并萘噻吩更快的褪色速率、红移和更高的性能评级。还揭示了包含光致变色材料的光致变色组合物和物品，例如光学元件。

  The present invention relates to photochromic materials that include a photochromic compound that includes a photochromic substituent (e.g., an indeno-fused naphthopyran) and at least one pendent silane group, which is bonded to the photochromic substituent. The pendent silane groups are selected from certain pendent siloxy-silane groups and/or pendent alkoxy-silane groups represented by general formulas (I) and/or (II) as described in further detail herein. The present invention also relates to photochromic articles, such as photochromic optical elements (e.g., photochromic lenses), and photochromic coating compositions (e.g., curable photochromic coating compositions), that include the photochromic materials of the present invention. The photochromic materials of the present invention have improved compatibility with compositions into which they may be incorporated, for example, coating compositions, such as urethane coating compositions.

  本发明涉及包括具有光致变色取代基（例如，吲哚并环戊基吡喃）和至少一个侧基硅烷基的光致变色化合物的光致变色材料。侧基硅烷基从描述的通用式（I）和/或（II）表示的某些侧基硅氧烷基和/或侧基烷氧基中选择。本发明还涉及光致变色物品，例如光致变色光学元件（例如，光致变色透镜）和光致变色涂层组合物（例如，可固化的光致变色涂层组合物），其中包括本发明的光致变色材料。本发明的光致变色材料与可能加入其中的组合物（例如，涂层组合物，例如脲基涂层组合物）具有改进的相容性。
