The present invention relates to photochromic materials that include one or more indeno-fused naphthopyrans that have particular groups at the 7, 11, and 13 positions thereof, and at the position alpha to the oxygen of the pyran ring thereof. With some embodiments, hydrogen or an alkoxy group is bonded to the 7 position, an optionally substituted phenyl is bonded to the 11 position, two alkyl groups are bonded to the 13 position, and two optionally substituted phenyl groups are bonded to the position alpha to the oxygen of the pyran ring of the indeno-fused naphthopyran compound. The 13 position of the indeno-fused naphthopyrans is free of ether groups in which an ether oxygen is bonded to the 13 position, and hydroxyl. The present invention also relates to photochromic articles and compositions that include such indeno-fused naphthopyrans.
本发明涉及包括一个或多个具有特定基团的吲哚螺合萘并吡喃的光致变色材料,其中该基团位于其7、11和13位置以及其吡喃环氧位的α位置。在某些实施例中,氢或烷氧基与7位置结合,可选取代苯基与11位置结合,两个烷基与13位置结合,并且两个可选取代苯基与吲哚螺合萘并吡喃化合物的吡喃环氧位的α位置结合。吲哚螺合萘并吡喃的13位置不含有醚基,其中醚氧原子与13位置结合,以及羟基。本发明还涉及包括这种吲哚螺合萘并吡喃的光致变色物品和组合物。
