    摘要： Described are novel photochromic pyrano-fused naphthopyran compounds, examples of which are naphthopyran compounds having a substituted or unsubstituted 'S' pyran ring, the 3,4 positions of which are fused to the f side of the naphtho portion of the naphthopyran, and certain substituents at the 2-position of the 'T' pyran ring. Certain substituents may also be present at the number 5, 7, 8, 9, 10, 11 or 12 carbon atoms of the compounds. These compounds may be represented by graphic formula (I). Also described are polymeric organic host materials that contain or that are coated with such compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans, and spiro(indoline) type compounds.

    摘要： Described are novel reversible photochromic 2H-naphtho[1,2-b]pyran compounds, examples of which are compounds having certain substituents at the number 5 carbon atom of the naphtho-portion of the naphthopyran and at the 2-position of the pyran ring. Certain substituents may also be present at the number 6, 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.

    摘要： Described are novel photochromic six-membered heterocyclic-fused naphthopyran compounds, examples of which are naphthopyran compounds having a substituted or unsubstituted six-membered heterocyclic group fused to one side of the naphtho portion of the naphthopyran and having certain substituents at the position ortho to the oxygen atom of the naphthopyran ring. These compounds may be represented by graphic formula (A). Also described are polymeric organic host materials that contain or that are coated with such compounds or combinations thereof with complementary photochromic compounds, e.g., certain other naphthopyrans, benzopyrans, and spiro (indoline)type compounds.
