Multitarget synthetic strategies to access novel photochromic 3H-naphtho[2,1-b]pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3H-naphtho[2,1-b]pyrans display good photochromic properties with reversible generation of photomerocyanines, which exhibit mainly orange/red hues. Photochromic parameters including photocolorability and persistence of color vary tremendously on structural modification of the naphthopyran core.

新型吡啶基取代的萘并吡喃的合成和光致变色。

描述了多目标合成策略,以访问新型的吡啶基单元修饰的光致变色3 H-萘[ 2,1- b ]吡喃。新的吡啶基取代的3 H-萘[ 2,1 - b ]吡喃具有良好的光致变色特性,可逆生成的光金属花青素主要表现为橙色/红色。光致变色参数(包括光致变色性和颜色的持久性)在萘并吡喃核的结构修饰上有很大差异。
