This review covers all aspects of 9-borafluorene chemistry, from the first attempted synthesis in 1960 to the present. This class of molecules consists of a tricyclic system featuring a central antiaromatic BC ring with two fused arene groups. The synthetic routes to all 9-borafluorenes and their adducts are presented. The Lewis acidity and photophysical properties outlined demonstrate potential utility as sensors and in electronic materials. The reactivity of borafluorenes reveals their prospects as reagents for the synthesis of other boron-containing molecules. The appealing traits of 9-borafluorenes have stimulated investigations into analogues that bear different aromatic groups fused to the central BC ring. Finally, we offer our views on the challenges and future of borafluorene chemistry.
本综述涵盖了 9-硼芴化学的各个方面，从 1960 年首次尝试合成到现在。这一类分子由一个三环体系组成，具有一个中心反芳香性的 BC 环和两个融合的芳烃基团。介绍了所有 9-硼芴及其加合物的合成路线。概述的路易斯酸度和光物理性质表明它们有望作为传感器和电子材料使用。硼芴的反应性揭示了它们作为合成其他含硼分子的试剂的前景。9-硼芴吸引人的特性激发了对与中环 BC 环融合的不同芳香基团的类似物的研究。最后，我们对硼芴化学的挑战和未来提出了看法。
