The present invention relates to photochromic materials that include certain indeno-fused naphthopyrans. The indeno-fused naphthopyrans have an amino group (e.g., a piperidino or morpholino group) bonded to the 6-position and an optional halo group (e.g., fluoro) bonded to the 11-position thereof. The photochromic materials of the present invention may have a closed-form electromagnetic radiation absorption spectrum that is shifted to longer wavelengths (e.g., wavelengths of greater than 390 nm), relative to comparable photochromic materials. The present invention also relates to optical elements, such as eyeglasses, that include the photochromic materials of the present invention.
本发明涉及包括某些吲哚并螺[3,3,3]己喹喙的光致变色材料。这些吲哚并螺[3,3,3]己喹喙在6位与氨基团(例如哌啶基或吗啉基)键合,并且在11位可能与卤素基团(例如氟基)键合。本发明的光致变色材料可能具有闭合形式的电磁辐射吸收光谱,其相对于类似的光致变色材料向更长波长(例如大于390纳米的波长)移动。本发明还涉及包括本发明的光致变色材料的光学元件,例如眼镜。
