Described are novel reversible photochromic naphthopyran compounds, examples of which are compounds substituted at the 3 position of the pyran ring with (i) an aryl substituent and (ii) a phenyl substituent having a 5- or 6-member heterocyclic ring fused at the number 3 and 4 carbon atoms of the phenyl substituent. 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的萘吡喃化合物,其示例是在吡喃环的3位上取代的化合物,其中(i)是芳基取代基,(ii)是苯基取代基,在苯基取代基的3和4碳原子上融合有5-或6-成员杂环环。还描述了含有或涂有这种化合物的有机宿主材料。还描述了包含新型萘吡喃化合物或其与互补光致变色化合物(例如螺(indoline)型化合物)组合的眼镜镜片或其他塑料透明物品。
