Title (DE) PHOTOCHROME DIARYL-3H-NAPHTHOPYRANE
(EN) PHOTOCHROMIC DIARYL-3H-NAPHTHOPYRANES
(FR) DIARYL-3H-NAPHTHOPYRANNES PHOTOCHROMES
Abstract:
(DE) Beschrieben wird eine photochrome Verbindung mit Diaryl-3H-naphthopyranstruktur, die in 8-Stellung einen über ein Stickstoffatom verknüpften Heterocyclus aufweist, wobei der Heterocyclus als Substituenten auch eine HALS-Verbindung aufweisen kann, oder der Heterocyclus selbst in Form einer HALS-Verbindung ausgebildet sein kann. Weiterhin wird eine photochrome Verbindung mit Diaryl-3H-naphthopyranstruktur beschrieben, die in 8-Stellung eine über ein N-Atom und eine Alkylbrücke verknüpfte HALS-Verbindung aufweist.
(EN) The disclosure relates to a photochromic compound with diaryl-3H-naphthopyrane structure which in position 8 has a heterocycle linked via a nitrogen atom. The heterocycle can also have a hindered amine light stabilizer (HALS) compound as substituent or can take the form of a HALS compound. Also described is a photochromic compound with diaryl-3H-napththopyrane structure with a HALS compound in position 8 linked via a nitrogen atom and an alkyl bridge.
(FR) L'invention concerne un composé photochrome à structure diaryl-3H-naphthopyranne qui comporte, en position 8, un hétérocycle lié par l'intermédiaire d'un atome d'azote, ledit hétérocycle pouvant également comporter, comme substituant, un composé photostabilisant d'amine encombrée (HALS), ou ledit hétérocycle pouvant se présenter sous forme de composé photostabilisant d'amine encombrée (HALS). L'invention concerne en outre un composé photochrome à structure diaryl-3H-naphthopyranne, qui comporte, en position 8, un composé lié par l'intermédiaire d'un atome de N et d'un pont alkyle.
