Herein, we describe the synthesis of unsymmetrically substituted dibenzo[]furazano[3,4-]quinoxalines by intramolecular cyclization through direct transition metal-free C-H functionalization. The electrochemical and photophysical properties for several polycycles have been measured. In thin films of the dibenzo[]furazano[3,4-]quinoxalines, hole mobility is in the order of 10 cm V s. The results show that the HOMO and LUMO energy levels are appropriate for using the compounds as hole-transport materials in thin-film devices, in particular, organic and perovskite solar cells.
在此，我们描述了通过直接无过渡金属的C-H官能化进行分子内环化来合成不对称取代的二苯并[]呋喃并[3,4-]喹喔啉。已测量了几种多环化合物的电化学和光物理性质。在二苯并[]呋喃并[3,4-]喹喔啉的薄膜中，空穴迁移率约为10 cm² V⁻¹ s⁻¹。结果表明，最高占据分子轨道（HOMO）和最低未占据分子轨道（LUMO）能级适合将这些化合物用作薄膜器件，特别是有机和钙钛矿太阳能电池中的空穴传输材料。
