新型多环芳烃Bisanthene衍生物的合成研究进展

Synthesis of Bisanthene-Based Polycyclic Aromatic Hydrocarbons

多环芳烃共轭体系作为一种新型的有机光电材料,在有机电子学领域占据着举足轻重的地位.其家族成员Bisanthene具有优异的特性,拥有相对较小的分子能级及平面共轭双烯结构,可以进行化学修饰来合成多种新型多环芳烃.根据Bisanthene结构的特殊性,可以对其短轴纵向修饰以及长轴横向修饰,从而扩大其π电子共轭体系,提高分子的溶解性及稳定性.综述了Bisanthene衍生物的合成方法及性质的研究进展,并对今后的研究方向进行了展望.

Polycyclic aromatic hydrocarbons （PAHs） with extended n-conjugation play a significant role as novel organic optoelectronic materials. As a family member ofPAHs, bisanthene possesses unique properties and features such as small band gap and planar diene structure, which benefits it as a key building block to construct new PAHs by appropriate design and chemical modification. For example, the modifications along with its short-axis and long-axis could not only enlarge its n-conjugated path route, but also improve the solubility and stability. The recent research progress in the synthesis and properties ofbisanthene derivatives is summarized, and the future research of this field is prospected.
