OXIDIZED DIARYLETHENE PHOTOCHROMIC COMPOUNDS AND POLYMERS THEREOF

摘要

The present invention on oxidized diaryl about butene photochromic compounds and their polymers, and more particularly to a novel photochromic compounds and their polymers, as well as color change to the light having a fluorescent function at the same time, wherein the photochromic material when containing a photochromic compound or a polymer, so compared to the conventional optical material excellent in fluorescence efficiency with performance photochromic then can be applied to the fields of optical recording medium, an optical switch, the photosensitive drum, the print element, the fiber and the optical element a diaryl oxide represented by the general formula (1) and formula (2) relates to a butene photochromic compounds and their polymers.; In Formula ^{1, Z 1, Z 2,} Ar 1 and Ar ² are as defined in the detailed description of the invention.; In Formula ^{2, Z 1, Z 2,} Ar 6 and Ar ^7, A is as defined in the detailed description of the invention.
