    摘要： The present invention relates to photochromic benzopyranes and the use thereof in plastic materials of all types, particularly for ophthalmic purposes. The compounds according to the invention are photochromic benzopyrane compounds, wherein a multi-core aromatic compound is linked to the 5th and 6th positions of a benzopyrane, wherein the linkage in the 6th position occurs directly, and the linkage in the 5th position occurs via a one- or two-atom bridge.

    摘要： The invention relates to a photochromic plastic object which is composed of a transparent polymeric synthetic material, into or onto which at least one substantially mesoporous inorganic host structure that is provided with one or several embedded organic photochromic dye molecules is introduced or applied so as to form a photochromic nanocomposite material. According to the invention, photochromic nanocomposite particles or photochromic nanocomposite structures are used for creating color as opposed to prior art in which photochromic organic dyes are added to the monomer mixture/prepolymer of synthetic glass in a molecular form.
