General Description

4-Morpholino-2-naphthol, also known as 2-Naphthol-4-morpholinyl Ether, is a chemical compound with the formula C14H15NO. It belongs to the group of organic substances called phenols and phenol derivatives, which are aromatic compounds that contain a phenol group. It is used in organic synthesis, specifically in the production of dyes, as it has the ability to accept and donate hydrogen bonds during chemical reactions. Its molecular structure comprises a naphthalene moiety linked to a morpholine group. As with other chemicals, handling 4-Morpholino-2-naphthol should be done with caution due to potential health and environmental hazards.

Photochromic compositions, photochromic compounds (co)polymer matrices

The object of the present invention is a photochromic composition incorporating:+2-(p-dimethylaminophenyl)2-(p-methoxyphenyl)-5-methyl-7,9-dimethoxy-[2H]-naphtho[1,2-b]pyran (compound (I)),and+3-(p-methoxyphenyl)-3-phenyl-6-morpholino-3H-naphtho-[2,1-b]pyran (compound (II)).The invention also relates to said compounds (I) and (II) per se, (co)polymer matrices containing same, advantageously in a mixture, as well as finished products constituted wholly or in part of such matrices and/or containing one and/or the other of said compounds (I) and (II).

Photochromic naphthopyran compounds

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, and at the 6 position of the naphthyl portion of the naphthopyran compound with a nitrogen-containing heterocyclic ring. 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.
