Described are novel reversible photochromic 2H-naphtho[1,2-b]pyran compounds, examples of which are compounds having certain substituents at the 5 and 6-positions of the naphtho portion of the naphthopyran and at the 2-position of the pyran ring, e.g., 2,2-bis(4-methoxy phenyl)-5-methoxycarbonyl-6-morpholino-2H-naphtho[1,2-b]pyran. Certain substituents may also be present at the number 7, 8, 9 or 10 carbon atoms of the naphtho portion of the naphthopyran. Also described are organic host materials that contain or that are coated with such compounds. Articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel naphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., spiro(indoline) type compounds, are also described.
描述了一种新型可逆光致变色2H-萘并[1,2-b]吡喃化合物,例如,在萘并吡喃的5和6位以及吡喃环的2位具有特定取代基的化合物,例如2,2-双(4-甲氧基苯基)-5-甲氧羰基-6-吗啉基-2H-萘并[1,2-b]吡喃。在萘并吡喃的7、8、9或10碳原子上也可能存在某些取代基。还描述了含有这些化合物或涂有这些化合物的有机宿主材料。还描述了包含新型萘并吡喃化合物或与补充光致变色化合物(例如螺(吲哚)型化合物)组合的眼镜镜片或其他塑料透明物品。
