摘要
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 hydrogen or a halo group (e.g. fluoro) bonded to the 11 position thereof. The photochromic materials of the present invention can 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. Formula (I).
