    摘要： Various non-limiting embodiments disclosed herein relate to photochromic materials having extended pi-conjugated systems. For example, various non-limiting embodiments disclosed herein provide a photochromic material, such as an indeno-fused naphthopyran, which comprises a group that extends the pi-conjugated system of the indeno-fused naphthopyran bonded at the 11-position thereof. Further, the photochromic materials according to certain non-limiting embodiments disclosed herein may display hyperchromic absorption of electromagnetic radiation as compared to conventional photochromic materials and/or may have a closed-form absorption spectrum that is bathochromically shifted as compared to conventional photochromic materials. Other non-limiting embodiments relate to photochromic compositions and photochromic articles, such as optical elements, made using the disclosed photochromic materials, and methods of making the same.

    摘要翻译： 本文公开的各种非限制性实施方案涉及具有延伸的π-共轭体系的光致变色材料。 例如，本文公开的各种非限制性实施方案提供光致变色材料，例如茚并稠合的萘并吡喃，其包含延伸在其11位键合的茚并稠合的萘并吡喃的π-共轭体系的基团。 此外，与常规光致变色材料相比，根据本文公开的某些非限制性实施方案的光致变色材料可以显示电磁辐射的超色吸收和/或可以具有与常规光致变色材料相比被红移的闭合形式的吸收光谱。 其它非限制性实施方案涉及光致变色组合物和光致变色制品，例如使用所公开的光致变色材料制备的光学元件及其制备方法。
