  Described are photochromic 2H-naphtho[1,2-b]pyrans characterized by two adjacent moderate to strong electron donor substituents at the 7 and 8 positions, a moderate to strong electron withdrawing substituent at the 5 position, and at the 2 position, one substituent that is a weak electron donor and another substituent that is a weak to moderate electron donor. An optional substituent is located at the 6 position and each of the positions may have reactive substituents that enable the photochromic material to be more compatible with the host polymer. The selection and placement of the aforementioned substituents being done on the naphthopyran to demonstrate a lambda max of less than 490 nanometers in the Photochromic Performance Test. The selection and placement of substituents also enables the balancing of photochromic properties, such as the intensity, as measured in the Photochromic Performance Test. Also described are polymeric organic host materials that contain or that are coated with such naphthopyrans or combinations thereof with complementary photochromic compounds to produce photochromic articles such as ophthalmic lenses.

  [EN] Described are photochromic 2H-naphtho[1,2-b]pyrans characterized by two adjacent moderate to strong electron donor substituents at the 7 and 8 positions, a moderate to strong electron withdrawing substituent at the 5 position, and at the 2 position, one substituent that is a weak electron donor and another substituent that is a weak to moderate electron donor.

  [FR] L'invention concerne des composés 2H-naphto[1,2-b]pyrannes photochromiques caractérisés par deux substituants donneurs d'électron adjacents modérés à forts aux positions 7 et 8, un substituant accepteur d'électron modéré à fort en position 5, et, en position 2, un substituant qui est un faible donneur d'électron et un autre substituant qui est un donneur d'électron faible à modéré. Un substituant facultatif est prévu en position 6, et chacune des positions peut comporter des substituants réactifs qui rendent la matière photochromique plus compatible avec le polymère hôte. La sélection et le placement des substituants mentionnés est mise en oeuvre sur le naphtopyranne de sorte que celui-ci présente une valeur lambda maximale inférieure à 490 nanomètres dans le test d'efficacité photochromique. La sélection et le placement des substituants permet aussi d'équilibrer des propriétés photochromiques telles que l'intensité, mesurée par le test d'efficacité photochromique. L'invention concerne également des matières organiques polymères hôtes qui contiennent de tels naphtopyrannes ou sont revêtues de ceux-ci, ou des combinaisons de celles-ci avec des composés photochomiques complémentaires qui permettent de produire des articles photochromiques tels que des lentilles ophtalmiques.
