Photochromic Indeno-Fused Ring Pyran Compounds

摘要

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) Z2 is a group N—R13 in which R13 is a group L, and (ii) optionally at least one R1 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).
