The present invention relates to photochromic indeno-fused ring pyran compounds represented by the following Formula (I-A):
The present invention also relates to photochromic dichroic compounds, such as represented by Formula (I-A), in which (i) Z
2
is a group N—R
13
in which R
13
is a group L, and (ii) optionally at least one R
1
independently for each n is selected from a group L, in which the group L independently in each case is a lengthening group that provides the photochromic compound with dichroic properties, in accordance with some embodiments. The present invention also relates to photochromic articles, such as photochromic ophthalmic articles, that include one or more photochromic compounds according to the present invention, such as represented by Formula (I-A).
本发明涉及由以下式(I-A)表示的光致变色吲哚融合环吡喃化合物。本发明还涉及光致二向色化合物,例如由式(I-A)表示,其中(i)Z2是一个N—R13基团,其中R13是一个L基团,以及(ii)对于每个n,可选地至少选择一个R1,每种情况下独立选择自L基团,其中每种情况下L基团是一个提供光致化合物二向色性能的延伸基团,符合某些实施例。本发明还涉及光致物品,例如光致眼科物品,包括根据本发明的一个或多个光致化合物,例如由式(I-A)表示。
