The synthesis of 3H-naphtho[2,1-b]pyrans linked to mono-, di-, or terthiophene via an acetylenic junction is described (Schemes 2 and 3). The synthetic approaches involve successive Sonogashira coupling reactions. The photochromic properties in solution of these novel materials were investigated under continuous irradiation.
描述了通过炔键连接到单-、二-或三噻吩的 3H-萘并[2,1-b]吡喃的合成(方案 2 和 3)。合成方法涉及连续的 Sonogashira 偶联反应。在连续辐照下研究了这些新型材料在溶液中的光致变色特性。
