Described are novel reversible photochromic indenonaphthopyran compounds, examples of which are 2H-naphtho[1,2-b]pyrans characterized by having a substituted or unsubstituted indeno group fused at the 2,3 positions of the group to the 1 side of the 2H-naphthopyran. The compounds also have substituents at the 3 position of the pyran ring. Substituents may also be present at the number 5, 6, 7, 8, 9, 10, 11, 12, or 13 carbon atoms of the compounds. These compounds may be represented by the following graphic formulae:

Also described are various substrates, e.g., paper, glass, organic polymeric materials, etc., that contain or that are coated with such compounds. Optically clear articles such as ophthalmic lenses or other plastic transparencies that incorporate the novel indenonaphthopyran compounds or combinations thereof with complementary photochromic compounds, e.g., indenonaphthopyrans, naphthopyrans, benzopyrans, oxazine-type compounds, etc., are also described.
所述的是新型可逆光致变色茚并萘吡喃化合物,其实例为 2H-萘并[1,2-b]吡喃,其特征在于具有一个取代或未取代的茚并基团,该基团在 2、3 位与 2H-萘并吡喃的 1 侧融合。这些化合物还在吡喃环的 3 位上具有取代基。在化合物的 5、6、7、8、9、10、11、12 或 13 个碳原子上也可能存在取代基。这些化合物可以用以下图式表示:
