We describe the synthesis and photophysical properties of tetraarylnaphthidines. Our synthetic approach is based on an iron-catalyzed oxidative C–C coupling reaction as the key step using a hexadecafluorinated iron–phthalocyanine complex as a catalyst and air as the sole oxidant. The N,N,N’,N’-tetraarylnaphthidines proved to be highly fluorescent with quantum yields of up to 68%.

四芳基萘啶的铁催化合成、结构和光物理性质

我们描述了四芳基萘啶的合成和光物理特性。我们的合成方法基于铁催化的氧化 C-C 偶联反应作为关键步骤，使用十六氟化铁 - 酞菁配合物作为催化剂，空气作为唯一氧化剂。N,N,N',N'-四芳基萘烷被证明具有高荧光性，量子产率高达 68%。
