尽管四配位有机硼配合物作为荧光材料已被广泛应用, 但硼中心上连接有两个芳基的配合物的合成方法仍然较少. 该类化合物的合成一般需要使用敏感的有机金属试剂. 本工作使用市售可得、化学稳定的芳基三氟硼酸钾盐作为二芳基硼结构的来源, 以8-氨基喹啉作为螯合配体, 以中等至优异的产率获得了一系列先前难以制备的二芳基硼络合物. 此外, 对所得配合物的密度泛函理论计算研究揭示了其分子轨道分布.

Despite the wide application of four-coordinate organoboron compounds as fluorescent materials, the synthesis of such complexes, which contain two aryl groups on the boron centers, is relatively limited by the need for sensitive organometallic reagents. Herein, using stable and commercially available aryl trifluoroborate potassium salts as complexation reagents, a series of aminoquinolate-framed diarylboron complexes, which were difficult to access previously, have been obtained in moderate to excellent yields. Furthermore, density functional theory (DFT) study of the obtained complex shows its molecular orbital distribution.
