中国科学院大学黄辉课题组在结构复杂的多环芳烃的合成研究中取得了新进展。该成果近日发表于国际著名期刊《德国应用化学》。

该研究展示了一种合成具有烷基和芳基取代的含杂原子的多环芳烃（H-PAHs）的简单合成路线。

通过多取代烯烃的形成和环化这两个关键步骤，研究人员成功地合成了三种含杂原子的多环芳烃，包括含杂原子的荭（H-rubicene）、角状苯并噻吩（ABT）和茚并噻吩（IDT），并对含杂原子的角状苯并噻吩和荭进行了包括单晶X射线衍射、核磁共振、紫外-可见吸收光谱、循环伏安法、瞬态吸收和单晶有机场效应管（single crystal OFET）在内的全面表征。

Issue&Volume:

Abstract: Simple synthetic routes for heteroatom‐containing polycyclic aromatic hydrocarbons (H‐PAHs) with alkyl and aryl substitution were demonstrated. Three H‐PAHs including heteroatom containing rubicenes (H‐rubicenes), angular‐benzothiophenes (ABTs), and indenothiophene (IDTs) were successfully synthesized through two key steps including polysubstituted olefins formation and cyclization. Specifically, ABT and H‐rubicenes were comprehensively investigated by single‐crystal X‐ray diffraction, NMR, UV‐vis absorption, cyclic voltammetry, transient absorption and single crystal OFET measurements.
