一类光致变色材料的合成

Synthesis of a Class Photochromic Materials

光致变色材料是一种用途广泛的有机功能材料,它在紫外光照射下开环形成有色体,引起材料外观颜色发生,可应用于变色材料,具有很高的商业价值。为此,讨论合成3,3-二苯基-3H-萘并[2,1-6]吡喃光致变色材料,它是一种具有较好光致变色性质的黄色光致变色化合物。

Because of its specialty in structure and properties , photochromic materials are widely used in the science and daily life. The UV-Light , then forms chromoplast. The interaction brings about appearance-color changes of the material, that can be applied to discoloration materials . The application has very highly commercial value. For this reason, is discussed the synthetic method of the discoloration material 3,3-diphenyl-3H-naphtho^[2,1-6] pyrans. Naphtha pyrans is a yellow photochromic compound which has fairly good photochromic property.
