Multitarget synthetic strategies to access novel photochromic 3-naphtho[2,1-]pyrans decorated with pyridyl units are described. The new pyridyl-substituted 3-naphtho[2,1-]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.
描述了一种用于合成新型吡啶基修饰的 3-萘并[2,1-b]吡喃光致变色化合物的多靶点合成策略。这些新的吡啶取代的 3-萘并[2,1-b]吡喃具有良好的光致变色性能，可可逆地生成光致变色体，呈现出主要为橙色/红色的色调。光致变色参数，包括光致变色性和颜色的持久性，在萘并吡喃核心的结构修饰上有很大的变化。
