| titleOfInvention | Photochromic spiropyran compounds |
| abstract | Described are a series of novel benzospiropyran and naphthospiropyran compounds in which a norcamphor group (or its alkyl-substituted homologues) or a tricyclodecane group (or its alkyl-substituted derivatives) are appended at the 2-positiion of the benzospiropyran or naphthospiropyran ring. Also described are organic host materials that contain or that are coated with materials containing such compounds. Articles, such as ophthalmic or plano lenses, that incorporate the novel pyran compounds or combinations of the novel pyran compounds with other complementary photochromic compounds are described. |
