"Fused" BN indoles are an emerging class of boron-containing indole mimics, featuring geometric structure and electophilic aromatic substitution reactivity similar to those of indoles but exhibiting distinct electronic structure, leading to unique optoelectronic properties. Herein we report the synthesis of the parent N-H BN indole and provide a head-to-head comparison of the structural features, pK(a) values, and optoelectronic properties of this hybrid organic/inorganic indole with the classic natural indole.
“Fused” BN 吲哚是一类新兴的含硼吲哚类似物,其几何结构和亲电芳香取代反应活性与吲哚相似,但展现出独特的电子结构,从而导致独特的光电性质。在此,我们报告了母体N-
H BN 吲哚的合成,并对这种杂化有机/无机吲哚与经典天然吲哚的结构特征、pKa值和光电性质进行了头对头比较。
